I have a simple hit box system in the works. An head hitbox entity (passable for now) is created by the enemy entity and aligned to the head every frame - this is done successfully when the enemy entity moves. However, when the entity plays its death animation, the head entity does not move according to the animation. here is code:

Code:

---

 

function me_die()
{
	var die_percentage = 0;
		while (die_percentage >= 0) // death_percentage will range from 0 to 100 here
    { 
       ent_animate(my, "DeathA", die_percentage, 0); // "death" one-shot animation 
       die_percentage += 5 * time; // 3 = animation speed for "death"
       wait (1); 
    } 	
}

function handle_hit_me()
{
	if (you.skill1 == 4)
	{
	effect(blood_cloud1,cloud_number,target.x,nullvector);
	my.skill20 -= 10;
	effect(blood_dropsspezial,blood_dropsAnzahlPartikel,target.x,nullvector);
	if (my.skill20 <= 0)
	{
	me_die();
	my.passable = on;
	}
	}
}

function hit_head()
{
	var target_look;
	var target_ver;
	my.passable = on;
	while(you)
	{
		vec_for_vertex (target_ver, you, 240);
		vec_for_vertex (my.x, you, 239);
		vec_sub(target_ver,my.x);
		vec_to_angle(my.pan,target_ver); // now MY looks at YOU
		wait(1);
	}
}

action dummy
{
	my.enable_impact = on;
	my.event = handle_hit_me;
	my.skill96 = 1;
	my.skill20 = 100;
	ent_create(headhitbox,my.x,hit_head);
	main_ai();
}

The code is very experimental at the moment and is not meant to be tidy. What I want to know, how do I make it align to animation? I know this is possible, it is mentioned in the vattach file which I downloaded when I first found that it didn't work, only to find it used the same concept.

I couldn't check the full code but it seems you are initialising death_percentage to 0 and in the while loop u have >= 0...so it could be exiting without executing your loop.I think you need a <= 100 in the loop.

sorry double post

It does execute the loop and the animation plays. (what you said just means die_percentage plays forever ). But I fixed that, and it doesn't fix my problem. The entity animates, and thus the position of the vertex must change based on this must change. But the hitbox doesn't move accordingly, so the animation is not altering the vertex position as it should.

oh indeed I screwed the expressions ..maybe your main_ai or any function that it calls has a proc_kill somehwhere ?

Nope no proc_kill. All it does, is index the AI (so it can be "seen" by enemies), and turning it to look towards enemies. In any case, commenting it out didn't help.

Are the vertex 239,240 on the head of the main entity and do they
animate along with the head when it dies ?
Also,try testing if the hitbox entity's while loop is
playing or not when the main entity dies.

i had problems with the "you" pointer yesterday too.

What happens if you write this:


function hit_head()
{
var target_look;
var target_ver;
my.passable = on;
my.skill1 = handle(you);
while(ptr_for_handle(my.skill1))
{
vec_for_vertex (target_ver, you, 240);
vec_for_vertex (my.x, you, 239);
vec_sub(target_ver,my.x);
vec_to_angle(my.pan,target_ver); // now MY looks at YOU
wait(1);
}
}

action dummy
{
my.enable_impact = on;
my.event = handle_hit_me;
my.skill96 = 1;
my.skill20 = 100;
ent_create(headhitbox,my.x,hit_head);
main_ai();
}

not sure if i wrote it correct

If you are trying Kikahu's code then also it will need a replacement for "you" (skill1 converted to entity pointer) within the while loop in these lines :-

vec_for_vertex (target_ver,you,240);
vec_for_vertex (my.x,you,239);

oh yeah, you are right, totally forgot about this part.

so just replace the "you" in the while with "ptr_for_handle(my.skill1)"

or simply right in the beginning of the while "you = ptr_for_handle(my.skill1)", should work too
