add more 'realism' to night scene with stars - 09/22/05 21:10

Hi!
For night scene may be usefull this piece, to add some 'blinking' stars:
Code:

...
bind <stars_.tga>;
sky skycube {
	type = <sky+6.tga>;
	flags = cube,visible;
	z=-5;													layer = 1;
}
sky stars {
	type=<stars.tga>;
	flags = dome,visible;
	scale_x=0.4;
	layer=3;
}
...
starter blinking_stars{
	while(1){
		ent_morph(stars,"stars_.tga");	//morph to shine stars
		waitt(random(15));			//play with this
		ent_morph(stars,"stars.tga");		//morph back
		waitt(random(9));			//play with this
	}
}

provide your stars.tga with 'normal' stars and stars_.tga, where some stars a slightly changed in size/brightness/color.
P.S.
You can use ent_morph with different engine objects, not bmaps only.

Thanks LionTs, you're always contributing, that's awesome. I think you need some closing parentheses on those waits though ))

Thatīs a bad code. Itīs not working the same on different pcs. I hope not all your codes are like that you published here.

wait(random(x)); <<< this will cause a flickering on a 3ghz comp minigame, and anything but not blinking on a 60khz cpu.

use sleep

I am afraid that many games here are full of such "not time fixed" code.

It's true I forget it. I'm posting from internet-cafe, not from my home, where my 3dgs installed. I looked at my code, I'm using waitt(random).
Sorry for that.
TO WING: Thank you, code changed.

Re: add more 'realism' to night scene with stars - 09/23/05 14:08

Yeah, but it worked. So, have I to use sleep instead ?

Another example.
We have same night and stars... Rain and moon...
Ok, add some more 'realism' - add flare to moon and change it when rain is on.
Code:

...
sky moon {										//moon
	type=<bmoon.tga>;
	flags=visible,transparent;//,transparent,overlay;
	alpha=100;
	x=500; //play with this and all below
	y=-130;
	z=100;
	scale_x=0.25;
	scale_y=0.25;
	scale_z=0.25;
	layer=5;
}
sky moon_flare {										//moon
	type=<bmoonflare.tga>;
	flags=visible,transparent;
	alpha=100;
	x=500; //pos to moon
	y=-130;
	z=110;
	layer=10;
}
...
//somewhere in your code
...
	while(1) {
		while(RAIN==on) {
//your rain code here
...
			if (moon.alpha > 50) { moon.alpha-=time; }
			moon.alpha = max(moon.alpha,0); 
			if (moon_flare.alpha > 50) { moon_flare.alpha-=time; }
			moon_flare.alpha = max(moon_flare.alpha,0); 
			wait(1);
		}
		if (moon.alpha < 100) { moon.alpha+=time;	}
		moon.alpha = min(moon.alpha,100); 
		if (moon_flare.alpha < 100) { moon_flare.alpha+=time;	}
		moon_flare.alpha = min(moon_flare.alpha,100); 
		wait(1);
  }

What is this ?
When rain is on - flare around moon slightly 'muted'.
Try, you'll like it

You shoudlnīt use waitt because itīs ld code. I thought itīs already removed. I hope you are working with the latest update. Noobs who get an error message with waitt could think itīs a typing mistake you made and write wait instead what will work but be wrong.

sleep(0.5); ~ 0.5 seconds

waitt will be removed within the next update. Use sleep instead.

Thanks for the cool effects code. All those little details add to the realism of the scene.

Thank you bupaje. Sorry for offtopic, but i have to say. Your photo(avatar)! This is me. This isn't a joke , my beard slightly smaller...
And I like beer. You are ?

Well I don't have the red nose and I shaved the beard. Use to wear it when I lived in a colder place. In California just itchy and now it has too much gray. I no longer drink - was only a social drinker; gave it up about 15 years ago.

From the "Post Your Photograph" thread in Morbius you can see my current mug shot.

To the waitt:

It is much more useful to me than sleep,
since I do not know how precise sleep will be in really
small time fractions.
I dont see a sense in removing waitt...

Re: add more 'realism' to night scene with stars - 09/25/05 22:27

Bupaje, I know now, how I'll looking after 10 years
To Damocles:
Well, you are right. sleep(0.005) ? May be try to measure sleep execution ?

Depending on how fast a PC is, if FPS is 300, then in a loop, you game will go through the loop 200 times.

If you still want to use waitt(), consider this:

Since there are 16 ticks per second with the waitt function, what you can do is use sleep. If you want a 16-tick precision from a waitt function, divide 1 by 16. That gives you 0.0625. So you can do this in a while loop:

sleep(0.0625);

But, there's another way: using a time variable for wait function.

wait(16) * time;

Since you want to have 16 ticks per second, all you have to do is substitute 16 for wait and multiply by time.

However, since I've tried the wait(16)*time with fps_max, I get different results. Same with sleep, too, so it's not a good ideal to use fps_max as there can be users who wanted to have a faster frame rates per second (in other words, smooth game play).

I'm not sure if the wait(16) * time can be affected by the frame rate, so I only test it with a blank level (a very small hollow cube) and my fps is pretty high. So go ahead and test it:

string _level = <time.wmb>;

font myFont = "Tahoma", 1, 16;
var myVar = 0;

Code:

panel myPanel
{
	digits = 20, 20, 2, myFont, 1, myVar;
	flags = visible;
}

function main()
{
	level_load(_level);;
	while(1) // Once the myVar goes up to 16, reset to 0 ans start again.
	{
		while(myVar < 16)
		{
			myVar += 1;
			sleep(0.0625); // This makes up 16 ticks.
		}
		myVar = 0;
	}
}


Change the code if you like (the level name, for example).

Thank you, Grayson Peddie. I'll try that.

I thought sleep made the whole program stop.. or is that changed?

man..i wish they would stop changing things like this.

freeze stops everything. Sleep never stopped everything and worked always like waitt (never saw it working different)

For what ? Blinking stars ?

Re: add more 'realism' to night scene with stars - 10/16/05 10:29

btw, @all "sleep" users:
i saw that thread, it might be important for you:
sleep replaced by wait

the posts of jcl are the important ones:
Quote:

Sleep wurde, wegen des gleichnamigen Windows-Befehls, sowieso ab 6.31.4 durch wait() ersetzt, so dass sich dieses Problem nicht stellt. Aber auch in 6.31.4 ist die Mindestwartezeit von einem Frame gewaehrleistet.

and
Quote:

wait (var);
Pauses the current function for a number of frame cycles or seconds.

Parameters:
var - number of frames when positive, wait time in seconds when negative. Maximum value is +/-1000.

Can someone upload some screenshots of this code working as I don't have time to try it myself.
