2.5D Spaceshooter - OpenSource - 11/26/08 12:37

Hey there!

I've started a little opne-source project for the 3dgs-users.
I started this little project for the newbies.
It should help to learn scripting little projects.

here is the first version of the code.
Code:
 


#include <acknex.h>
#include <default.c>

TEXT* help = {
	string = "TEST-PROGRAMM - CREATED BY MARCEL KLEE";
	red = 255; green=255; blue=255;
	flags=VISIBLE;
}


function plActor();


function main(){
	fps_max=60;
	wait(1);
	
	//Load the Environment
	level_load("");
	wait(3);
	
		ent_create("s1.mdl", vector(0,0,0),plActor);

}





function plActor()
{

var vecPos[3]   = {0,0,0};
var vecSpeed[3] = {0,0,0};
var vecAng[3]   = {0,0,0};

var mySpeed = 0;
var facCamAbst;

while(1){
mySpeed += key_force.y*time_step;
vecSpeed[1] = mySpeed*cos(my.pan);
vecSpeed[2] = mySpeed*sin(my.pan);
vecSpeed[3] = 0;

vecAng[1] -= key_force.x*10*time_step;

vec_add(vecPos[1], vecSpeed[1]);
accelerate(mySpeed, 0, 0.2);


my.pan  = vecAng[1];
my.tilt = 0;
my.roll = 0;

my.x = vecPos[1];
my.y = vecPos[2];
my.z = vecPos[3];

camera.x = my.x;
camera.y = my.y;
camera.z = my.z + 250 + facCamAbst;
camera.tilt= -90;
camera.roll= 0;
camera.pan = 0;

facCamAbst = mySpeed;
facCamAbst = abs(facCamAbst);


wait(1);
 }
}


with the arrow-keys you can handle the ship.
There is no level yet, so you can't see the ship-movement.
But you can load a level you made.

Some new code will follow...

cheers

Hey, great idea !

Well done

Re: 2.5D Spaceshooter - OpenSource - 11/26/08 15:55

thanx!

now a little introduction - how to use the code:


1- Create a new Project-folder on your PC.

2- Create a new ".c" -file (name for instance "game.c")
and copy the script into the file.

3- Create your space-ship mdl with med and save the model in the project-folder
The name of the space-ship model must be "s1.mdl" or you change the name in the script-file

4- That's it!

You can run your project. (one way to run the script -> drag and drop the game.c file to the acknex.exe
It will start automaticly.


The next i'll create is a code for a space-background.

Yes! Thank you.

Can you tell me how I would add MMike's Starfield to it? I can't figure it out but it might work with this.

Re: 2.5D Spaceshooter - OpenSource - 11/27/08 14:36

Hi Kevin!

I'll include my own version for the star-field.
Maybe,... today, or tomorrow,... i will update the script with the new features.

hey friends!

a new version of the code (without stars-background):

Code:
 

#include <acknex.h>
#include <default.c>



TEXT* help = {
	string = "TEST-PROGRAMM - CREATED BY MARCEL KLEE";
	red = 255; green=255; blue=255;

}


function plActor();


function main(){
	fps_max=60;
	wait(1);
	
	//Load the Environment
	level_load("");
	

	wait(3);


		ent_create("s1.mdl", vector(0,0,0),plActor);

}





function plActor()
{



var vecPos[3]   = {0,0,0};
var vecSpeed[3] = {0,0,0};
var vecAng[3]   = {0,0,0};

var mySpeed = 0;
var facCamAbst;

while(1){
mySpeed += key_force.y*time_step;
vecSpeed[1] = mySpeed*cos(my.pan);
vecSpeed[2] = mySpeed*sin(my.pan);
vecSpeed[3] = 0;

vecAng[1] -= key_force.x*10*time_step;

vec_add(vecPos[1], vecSpeed[1]);
accelerate(mySpeed, 0, 0.05);


my.pan  = vecAng[1];
my.tilt = 0;
my.roll = 0;

my.x = vecPos[1];
my.y = vecPos[2];
my.z = vecPos[3];

camera.x = my.x;
camera.y = my.y;
camera.z = my.z + 250 + facCamAbst;
camera.tilt= -90;
camera.roll= 0;
camera.pan = 0;

facCamAbst = mySpeed*12;
facCamAbst = abs(facCamAbst);



wait(1);
 }
}

the next days i will create the code for the background....
hold on!

hey there!

a new version. it inludes a star-field now...
its the first version of the star-field.

you only have to create a pcx map with the a pixel-size of 24x24. the color should be white. the name of the pcx file: "star.pcx"

the code:

Code:
 



#include <acknex.h>
#include <default.c>

BMAP* star_map = "star.pcx";

var star_gen_pos[3];


TEXT* help = {
	string = "TEST-PROGRAMM - CREATED BY MARCEL KLEE";
	red = 255; green=255; blue=255;
	flags=VISIBLE;
}


function plActor();
function part_alphafade(PARTICLE *p);
function effect_explo(PARTICLE *p);





function main(){
	fps_max=60;
vec_set(screen_color,vector(1,1,1)); 

	wait(1);
	
	//Load the Environment
	level_load("");
	

	wait(3);
		
				
	ent_create("s1.mdl", vector(0,0,0),plActor);
		

}





function plActor()
{



var vecPos[3]   = {0,0,0};
var vecSpeed[3] = {0,0,0};
var vecAng[3]   = {0,0,0};

var mySpeed = 0;
var facCamAbst;

while(1){
mySpeed += key_force.y*time_step;
vecSpeed[1] = mySpeed*cos(my.pan);
vecSpeed[2] = mySpeed*sin(my.pan);
vecSpeed[3] = 0;

vecAng[1] -= key_force.x*10*time_step;

vec_add(vecPos[1], vecSpeed[1]);
accelerate(mySpeed, 0, 0.05);


my.pan  = vecAng[1];
my.tilt = 0;
my.roll = 0;

my.x = vecPos[1];
my.y = vecPos[2];
my.z = vecPos[3];

camera.x = my.x;
camera.y = my.y;
camera.z = my.z + 250 + facCamAbst;
camera.tilt= -90;
camera.roll= 0;
camera.pan = 0;

facCamAbst = mySpeed*12;
facCamAbst = abs(facCamAbst);
		
		vec_set(star_gen_pos[1],my.x);

effect(effect_explo,10 * time_step,star_gen_pos[1],normal);


wait(1);
 }
}



////////////////////////////////////



function part_alphafade(PARTICLE *p)
{

     
if(num_particles > 300) {   p.lifespan -= 1*time_step; p.alpha -= 1*time_step; }   


}

function effect_explo(PARTICLE *p)
{
   var temp[3];
   p.lifespan = random(500) - 200;

   p.x = star_gen_pos[1] + random(400) - random(400);
   p.y = star_gen_pos[2] + random(400) - random(400);
   p.z = star_gen_pos[3] + random(400) - random(400);
   p.size = random(8)-4;
   
   p.alpha = 50 + random(25);
   p.bmap = star_map;
   p.flags |= (BRIGHT | TRANSLUCENT);
   p.event = part_alphafade; 
}



next i will optimize the code and create a background. the ship-physic will get more "realistic".

Re: 2.5D Spaceshooter - OpenSource - 12/12/08 18:40

Looking really good. I pasted the code into SED with my own model and star.tga and it worked excellently.

May I make a slight suggestion please, add a few comments in for people who are learning ??

Thank you for your great contribution

u wont believe me, but "you could use this code" for a game like gta 1 or gta 2. with some new variables and functions it would be possble.

but we create a "space-game". wink

hi maslone1,
great project!
I got one question though, what is this:
starmap.dds

I know that its an image file, could you maybe upload yours or describe how it should look?

thanks, I'm looking forward to contribute to this nice project.

Re: 2.5D Spaceshooter - OpenSource - 01/18/09 17:35

Hi Xarthor!

The starmap.dds have no function in this version of the code.
Maybe i'll use it for a new version of the star-filed... maybe.

I am sorry, i havent continued the work for this project.
I have to complete an another project first.

Re: 2.5D Spaceshooter - OpenSource - 01/18/09 17:42

Hi maslone,

Shooting & collisions would be good !

If you got a simple (expandable) game completed, I don't see why Conitec shouldn't ask you to add it to their work folder. The only complete game example there at the moment is Pong. This is crazy. People want starter examples in one place, they shouldn't have to hunt all over the forums, wiki, AUM etc, etc

why should you always be the one that updates the code? I thought this is intended to be an open-source community project? Or is it not?

1. It's his baby
2. He is a living god and we are not worthy to change his creation.

smile sorry, but i am not a god.
I am just a little programer, grafic-artist, music-artist....

My plan:

- Complete the other project (will be soon)

About the 2.5 Spaceshooter:
- Write a documentation for the script for better understanding
- add functions to the ship

cheers

Hey there!

I have some news:

I have changed the code. It is now "open-source-friendly".
Now i'll write a workshop, to show you how to use the code,
or to create new functions for the game.
Maybe coming weekend, its ready for download.

Hello!

Some news:

I have a new version of the code + new functions.
Now the code includes 2 kinds of gravity (maybe for planets or black-holes,.......)
For now, i have included 2 Planets-> one with gravity-force and one with anti-gravity-force.
The gravity-function could also be used for explosion or implosion - effects. Now i am working on the workshop and the manual....

Hey folks!


the new version:

File Front download 2_5D Spaceshooter V0_12


The workshop is still not finished....sorry...
but i hope this contribution help you to create own projects!

About the gameplay:
with the arow-keys you move the ship.
with "1" and "2" you select the weapon-type.
with space you fire the weapon you've selected.

with backspace you select "no weapon".

the weapon type 2 is not finished.
you can select it, but can't use it.
but u can add the weapon you want....


Cheers

Re: 2.5D Spaceshooter - OpenSource - 02/23/09 00:11

Odd. Selecting any weapon (even after publishing it) crashes the game for me (vista x64 Ultimate). Other than that, I can fly around just fine.

Re: 2.5D Spaceshooter - OpenSource - 02/23/09 19:32

hmmm... trial-version.
Maybe thats the reason.... i don't know....
Posted By: ortucis

Re: 2.5D Spaceshooter - OpenSource - 02/23/09 19:48

Yup, works fine with 7.7o trial. smile

Just to be sure, the ship moving into the golf balls when in their radius is intentional, right? (EDIT: My bad, it says in the code, Gravity Planet)

Also, I find it odd that instead of floating into the direction it was going when stopped, the ship starts moving upwards (well, top of the screen). Anyways, this looks really cool, so please keep updating it. laugh

*starts again.. pew pew pewww..*

Re: 2.5D Spaceshooter - OpenSource - 07/16/09 11:05

To give you news about the status of the 2.5D and the 3d space-game project.

I have recoded my script to 90% and the code works perfect (for me).
I have included new functions, you can use to calculate a complete 3d move with only 3 instructions.

You can setup the spaceship (acceleration, friction, other forces, weight,and so on).

A little move-able start-menue is also inlcluded.

An alpha version of my star-field effect = included.

Now i am working on the alpha version of the npc-ai.
(an ai only for a little battle).

After i have finished this, i use the code of the 3d version for the 2.5d version, so you can understand the scipt a lot easier.


One mor thing to say:
Before i release this 2 contributions, i have to talk with george or / and jcl, cause i wanna "win" the pro version of 3dgs (i have the com. version yet).
I hope this is possible......
This weekend i'll create a short video, to demonstrate the project.

now is a shader competition (if I'm not in a mistake)
Posted By: maslone1

Re: 2.5D Spaceshooter - OpenSource - 07/17/09 07:36

Yes, u are right.
The running contest is a shader-contest.

But maybe i can send it to george, an tell him to use it for the next contest..... ?
but i still have no answere from george.... maybe he is on holiday.
Posted By: maslone1

Re: 2.5D Spaceshooter - OpenSource - 07/17/09 14:42

Ok, jcl answered my question.

So the easier way is to wait at the right contest.
The other way is,... the project must be very popular -> and with a "Space-Game" i guess..... this would not get very popular.
But if i would create a "dvd-workshop", how to script a project like this,...
maybe a lot of newbies would be interested in this....

I'll think about it.....

But the video of my project still will come next week.

Re: 2.5D Spaceshooter - OpenSource - 10/16/09 07:25

Hey there!

So i have continued this project, and i am also do little tests with it to find bugs. So i fixed some bugs. But i have a little war with one BUG.
If i delete the player-ship and the player- function + reload the player with the player-function during i press (any) key, the value for the key keeps "1" (True). So i have to press the key again (for short) to reset it.
That means for me:
i have to write an own function that gives the key information to the player-ship. But isn't there an easy way.

while(xxxx){
......
.....
....
wait(1);}
key_force.x = 0;

-> is not possible (i have tested it, and the bug is still there....)

So do you know this bug in your projects? Have you other ideas to fix this?

Re: 2.5D Spaceshooter - OpenSource - 04/19/10 00:25

Hey Maslone1,

My wife upgraded my software last Christmas to A7 Commercial, so I am pleased to find your codebase. Rather than try and re-write my old C-Script space game from scratch in Lite-C, I am attempting to learn Lite-C as I fiddle with your source. Thanks for making it available.

Can you tell me what I would need to do to change the camera from 850 quants above the ship to first person perspective? I have modified F_cam_one, but I'm sure the keystrokes and other stuff also need to be changed. Not sure where or to what values...

function Cam1()
{
var cam_goal_dist; //Variable for the camera-distance
camera.z = Ships[1].z + 50; // cam-starting position

while(1){

camera.x = Ships[1].x;
camera.y = Ships[1].y;

cam_goal_dist = Ships[1].x + 850 + facCamAbst;
if(camera.x < cam_goal_dist) { camera.x += 1.8; } // the cam position follow the calculated cam_goal_dist variable
if(camera.x > cam_goal_dist) { camera.x -= 1.2; }
camera.tilt= 0; // -90 = look down
camera.roll= -90; // -90 = look forward
camera.pan = 0; // -90 = look sideways

wait(1);
}
}

Posted By: maslone1

Re: 2.5D Spaceshooter - OpenSource - 04/19/10 19:04

Hey MadMark!

Now the new changed code for you (and all other people):

Code:
function Cam1()
{
	
var cam_goal_dist = -40;					//Variable for the camera-distance
//camera.z = Ships[1].z + 850;		//thats the cam-starting position

camera.x = Ships[1].x;		//the x and y position is always the player x and y position
camera.y = Ships[1].y;
camera.z = Ships[1].z;	
	
while(1){	

rotate_rel(camera.x, Ships[1].x, Ships[1].pan, vector(cam_goal_dist,0,0));


if(key_u != 0) { cam_goal_dist += 2*time_step; }
if(key_i != 0) { cam_goal_dist -= 2*time_step; }


//camera.x = Ships[1].x;		//the x and y position is always the player x and y position
//camera.y = Ships[1].y;


/*
cam_goal_dist = Ships[1].z + 850 + facCamAbst;     // always the standard-distanze plus the variable distance
																	// how the variable-distance ist calculated you see in Pl_Ship.c

if(camera.z < cam_goal_dist) { camera.z += 1.8; }  // the cam position follow the calculated cam_goal_dist variable
if(camera.z > cam_goal_dist) { camera.z -= 1.2; }  // the reason why i use this: it brings more "dynamic" to the cam-movement
*/


camera.tilt= 0;
camera.roll= 0;
camera.pan = Ships[1].pan;


wait(1);	
 }
}



and the same code again, but this time without "nonsense":
Code:
function Cam1()
{
	
var cam_goal_dist = -40;					//Variable for the camera-distance

camera.x = Ships[1].x;		//the x and y position is always the player x and y position
camera.y = Ships[1].y;
camera.z = Ships[1].z;	
	
while(1){	

rotate_rel(camera.x, Ships[1].x, Ships[1].pan, vector(cam_goal_dist,0,0));

if(key_u != 0) { cam_goal_dist += 2*time_step; }
if(key_i != 0) { cam_goal_dist -= 2*time_step; }

camera.tilt= 0;
camera.roll= 0;
camera.pan = Ships[1].pan;


wait(1);	
 }
}



With the key " U " and " I " you can scroll / change the distance between camera and spaceship.
scroll down to "zero" and you have your 1person camera. or change the value "cam_goal_dist" to zero.

The important part is this function:
rotate_rel(camera.x, Ships[1].x, Ships[1].pan, vector(cam_goal_dist,0,0));

have a look at "F_math.c". there you see how ot calculates the position for the camera.


I hope it helps you.

But remember, thats simply the code for 2.5D. you cannot fly in complete 3d.
