Solved Help finding my coding error? - 11/16/08 05:16

Hello everyone, I am working on a game and I wasn't having problems until I converted to .c files for the scripts instead of .wdl because I needed to use panels, but now when I go to call a function I get an error.

The error I get is "Crash in Main" when I press the space bar, which calls the gun_shoot() action. Any help is appreciated, below is the code for the main and gun_shoot().

Code:

action gun_shoot()
{
	ent_create("muzzleflash.mdl", vector(my.x + 130, my.y, my.z + 9), gun_flash);
	ent_create("bullet.mdl", vector(my.x + 135, my.y, my.z + 9), ball_fall);
	my.tilt += 15;
	wait (10);
	my.tilt -= 15;
	set(my,PASSABLE);
}

function main()
{	
	level_load ("Test.wmb");
	wait (2);
	while(1)
	{
		if (key_space == 1)
		{
			gun_shoot();
			wait(2);
		}
		else
		{
			wait(1);
		}
	}
}

You are using the my pointer in the gun_shoot action. That is not allowed as gun_shoot is not attached to an entity. I guess what you wanted to do was:

Code:

action gun_shoot()
{
	ent_create("muzzleflash.mdl", vector(my.x + 130, my.y, my.z + 9), gun_flash);
	you = ent_create("bullet.mdl", vector(my.x + 135, my.y, my.z + 9), ball_fall);
	your.tilt += 15;
	wait (10);
	your.tilt -= 15;
	set(your,PASSABLE);
}

Thank you I will give that a shot. I was unaware that it was unattached to the entity since I set it as it's behavior in WDL, but none the less I shall try that code instead.

Is there any preference as to which is better, attaching the action to the entity, or using your instead of my?

Usually attaching an action to an entity is the better way as it is mor intuitive and understandable by more people. But at least maybe just a matter of personal preferences...

If you attach gun_shoot to an entity in WED this will of course work. But you're calling gun_shoot from the main function and the main function is of course not attached to anything.

Thank you, I see what I was doing wrong now. I didn't realize that since it was already attached to an entity that I didn't have to call it or anything. I moved the while loop into the gun_shoot action and it works now. I have to fix it though since for some reason my physics doesn't work right now that I moved from .wdl scripts to .c , but that is for another time.
