Black Screen when Test Runing in Lite-C

Hi,
I am trying to make a basic flight game. I am using the mig.hmp model from the litech workshops and a terrain level which is my own. I have borrowed a lot of code from the Litech workshops. When I test run it, the test run screen is black. but when I run the unmodifyed workshops, they seem to work fine. I deleated the #include <acknex.h> line at the top to see if I could get an error, but i still got the black screen. Does the black screen signify that there is an error with my code, or is there something wrong with the SED itself?

Here is my code:

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

VECTOR jet_speed;
ENTITY* jet;

function main()
{
fps_max = 140;
level_load("riverbed.hmp");
wait (2);
jet = ent_create ("mig.hmp", vector(-400,0,100), NULL);
ph_setgravity (vector(0,0, -386));
phent_settype (jet, PH_RIGID, PH_CUBE);
phent_setmass (jet, 3, PH_CUBE);
phent_setfriction (jet, 80);
phent_setdamping (jet, 40, 40);
phent_setelasticity (jet, 50, 20);
while(1)
{
jet_speed.x = 25 * (key_a - key_d);
jet_speed.y = 25 * (key_w - key_s);
jet_speed.z = 25 * (key_cuu - key_cud);
phent_addtorqueglobal (jet, jet_speed);
camera.x = jet.x - 300;
camera.y = jet.y;
camera.z = jet.z;
camera.tilt = -60;
wait (1);
}
}

For sure not. Errors are signalized through error messages. Make sure you run the file you're editing by pressing alt + f5. You have to include acknex.h. And it's default.c not defualt.c. Dunnow if that's just a typo here or in your code.

I'm actually having the same problem. I was making a game and I wanted a panel which needs to be in a .c file apparently. Anyway I made it .c and then physics didn't work so I put the physics commands in a separate .wdl, but now the level won't load.

I ran the lite-c workshop and it worked fine but when I put it into my script it doesn't work anymore.

Uhrwerk: I fixed that problem with #include but I still get a black screen. Also, it isn't just this script that gives, its anything that I try and make. Is is a bug in a7 or the free Lite-C version? Or could there be something wrong with my machine? I am using an Acer Notebook with a processor speed of 1.73GHz, 1014 MG of RAM, and a 32-bit operating system. I have Windows Vista.

level_load("riverbed.hmp");

i may be mistaken but to load a level does it not have to be the .wmb file that it loads? hmp is a terrain file

I am not sure. I am a beginner at programming. If so, how would I compile the terrain.hmp with a sky layer like blood_gorge+6.tga (that is from a workshop). Also, my computer does not recognize .tga and .pcx files. Is this a problem?

Never mind, i just read in help that Level_load accepts .hmp and .hmp was not listed in the help on ent_create.

Well, although I wouldn't use vista with an 1.7 GHz processor your laptop should be fine. And I've never heard of a bug like that. Please click on teh gears icon in the top toolbar of sed with the name "preferences" and ensure there is the file you want to run given under "Main Script to run / publish". A black engine window with nothing more is normally the result of an empty script. If that doesn't work, try a "printf("test");" at the very beginning of your main function. Is there then a message box appearing saying "test"? Also ensure you saved your file with the extension ".c".

There was no file given under "Main Script to run / publish" however, when I chose the script I have been wanting to run (I called it "flightscript.C")and then test run, I still get a black screen. The "printf("test");" didn't do anything.

Ensure you have the file name including the complete path to the script selected "Main Script to publish / run". Alternatively press Alt + F5 when you got your script opened in the editor. as long as the test message does not appear and you don't get error messages the engine is not running your script. If that doesn't fix the problem maybe your installation is corrupted. What version of Game Studio do you use?

I use the Free Lite0C version of the a7 game engine. I did as you suggested in you last post, but that did not fix anything. I guess it is possible that the installation was corrupted, however, it runs the workshops fine.
I can only open the samples to the workshops, not the actual tutorials themselves. When I try, it says "there is a problem with your internet connection", but my internet connection is working. I wondering if the 2 problems are related. I downloaded both in the "Download" section of this site.

Make sure you are using .c files, If you do not save your files like this
(filename.c) they will not save as a .c file. and when you try to run it you get a black screen.

Please try the following:
1. Open sed and create a new empty script.
2. Paste the follwing code into your empty script:
3. Save the script on your desktop (or somewhere else you get fast access to) under the name "test.c". Make sure you select .c file as extension under the file name in the save dialog and type the .c at the end of the file name additionally.
4. Click the gears icon to go to the preferences.
5. Select the file test.c that you have just created as "File to run / publish".
6. Check the checkbox that says diag. After cheking it there should be "-diag" under command line options.
7. Close the dialog with the ok button.
8. Hit the black triangle in the top toolbar to launch the engine.
9. There should be a message box popping up. (If it doesn't there is something wrong. Just continue with 10. We'll try to fix that...)
10. Go to your desktop or whereever you saved the file and look for a file "acklog.txt".
11. Post the content of this file in this thread.

Hi all,

Make sure you save your code with the .c at the end before you execute/compile it. Every time you make a change save it and the execute/compile. It works for me.

Sorry I have replayed sooner. I will do as you say when I get to my computer.

I did all of your steps in order and it wouldn't run. Here's what the acklog said:

I have had a few problems loading levels. The problem was (and still is) directory issues. For some reason i couldnt leave the MODELS for a specific level in ANY other folder, than the location of the scripts themselves.

Try putting all required files into a same directory and see how you go..

I am sorry. My fault. It has to be

Alrght, I did it again with the new code. Here are the results:

Excellent. You got it running. From here you can paste you own code line by line into the new file you just created. This way you can exactly identify the line that is causing the trouble.

It stops working at this line:

video_mode 7;

Here is the whole thing again:

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

VECTOR jet_speed;
ENTITY* jet;

function main()
{
video_mode 7;
set(pSplash,VISIBLE);
wait (3);

printf("test");
fps_max = 140;
level_load("riverbed.hmp");
ent_createlayer("blood_gsmall+6.tga", SKY | CUBE | VISIBLE, 0);
wait (2);
jet = ent_create ("mig.hmp", vector(-400,0,100), NULL);
ph_setgravity (vector(0,0, -386));
phent_settype (jet, PH_RIGID, PH_CUBE);
phent_setmass (jet, 3, PH_CUBE);
phent_setfriction (jet, 80);
phent_setdamping (jet, 40, 40);
phent_setelasticity (jet, 50, 20);
while(1)
{
jet_speed.x = 25 * (key_a - key_d);
jet_speed.y = 25 * (key_w - key_s);
jet_speed.z = 25 * (key_cuu - key_cud);
phent_addtorqueglobal (jet, jet_speed);
camera.x = jet.x - 300;
camera.y = jet.y;
camera.z = jet.z;
camera.tilt = -60;
wait (1);
}
}

i don't know what I did wrong or I would fix it. I don't get the black screen, just an error message. up until this point, it displayed both the message you gave me and the black screen.

it has to be "video_mode = 7;"

I changed it but I still get the black screen.

Please post the new content of the ackog.txt again...

But I know that that is not right because I changed the "video_mode 7;" to "video_mode = 7;" but it doesn't say that in teh acklog, which makes me think that is for someone reason not recognizing the enw code. Also, when I run, i don't get any errors like the acklog says, just the black screen. I am wondering if I just had a bad install (though I can still play the examples in the workshops).

If you corrected video_mode = 7; and this is really the file you're running then I am at the end of ideas. Sorry. Only advice: doublecheck everything written here so far.

Ok, thankyou for your help. I will try uninstalling and reinstalling both it and the workshops. If they still both act weird, then I will asume that it is my machine that is the problem. Again, thankyou for your help.

jet / mig is not .mdl!?
turn splash screen off
use [ code ] [ code ] tags

I checked and yes it is a .mdl, so I changed and still get the black screen. Does it matter that my script is a .wdl format? I thought it was the same as .c but I wanted to check.

Try turning off the splash screen, if it is on. (see above)
The file should probably be saved as .c, not .wdl (C-Script).
#include (<- this is .c -like syntax)

I did what you siad to turn off th splash screen, but that didn't seem to change anything. Also, how do I change a file from a .wdl to a .c? I can't change it in the properties and I can't change when I try to overite it in a new save.

open the .wdl file in SED. go to file>save and explicitly type ".c" after the filename, and press save. It should save as a seperate .c file.

You will want to rename or delete the .wdl file. If a .c file finds a .wdl file with the same name in the same directory it will attempt to read that file also.

Thankyou very much. I changed to a .c and I don't get a black screen anymore! I get error messages! YAY! But no worries, it's just my crappy code. It doesn't like my "set(pSPLASH, VISIBLE);" line, nor any other line after. But, Oh well. I will eventually figure all of that out. Oh, I figured out how to see those workshops. All I had to do was unblock them in the properties menu. Thanks again everyone for all of your help.
