Hi i got a major problem. my game crashes when i uses the effect function in C-Lite. i post a code snippet that uses the function.

Code:

---

  
// helper function: sets the vector to random direction and length
function vec_randomize (var* vec, var range)
{
   vec[0] = random(1) - 0.5;
   vec[1] = random(1) - 0.5;
   vec[2] = random(1) - 0.5;
   vec_normalize(vec,random(range));
}

// helper function: fades out a particle
function part_alphafade(PARTICLE *p)
{
   p.alpha -= 2*time_step;
   if (p.alpha <= 0) p.lifespan = 0;
}

// particle function: generates a fading explosion into vel direction
function effect_explo(PARTICLE *p)
{
   var temp[3];
   vec_randomize(temp,10);
   vec_add (p.vel_x, temp);
   p.alpha = 25 + random(25);
   p.bmap = "blood.tga";
   p.flags |= (BRIGHT | MOVE);
   p.event = part_alphafade; // change to a shorter, faster function
}

function hit()
{
	if(event_type == EVENT_ENTITY)
	{
		if(you.skill4 == 2)
		{
			you.skill3 -= 5;
		}
		if(you.skill66 == 0 && you != pl){
			you.pan = ang(my.pan + 90);
		}

		ent_morph(me, "blood.tga");
		my.flags |= OVERLAY;
	
		my.event=NULL;
			vec_scale(normal,10); // produce an explosion into the normal direction
		effect(effect_explo,1,my.x,normal);
			my.x = you.x;
		my.y = you.y;
	
		
		wait(1);
		c_move(my,vector(0-10*speed,0,0),nullvector,GLIDE);
		my.skill80=1;
	}

	if(event_type == EVENT_SURFACE)
	{
		my.event=NULL;

		wait(1);

		ent_remove(me);
	}
}

Which line is crashing? You can step through with the debugger to find out.

well ill fiex the crashing. but the problem is that it aint spawning any particles. thats the problem. so the question have changed. how to make it spawn particles. it chould work but it dosent.

Ok, then I need to reformulate the question: Why isn't it spawning particles?

Again, use the debugger to find out whether effect() is called at all, and whether or not the particle function is running.

yes it is. i checked that, u placed error("test"); before the effect. so its called. and i placed error("test2"); in the event thats called by the particles. and its called too

Ok, then the particles are spawned but you don't see them. They could be totally transparent, for instance, or at a different position than you expect.

Next things to check: remove all flags, have alpha at 100% and use an opaque bitmap until you see the particles.

well i try that. thank you. i reply when i got some result or no results at all
