Decals won't disappear

[darrenc182]

Decals won't disappear when freeing the entity. This use to work fine and it was the way I erased bullet decals after a certain amount of time. Does anyone know why the decals no longer disappear after the decal's entity is freed? Also is there a way to remove a decal after a certain time frame? I will post some code if needed upon request. Thanks in advance for all help and suggestions.

You could use/copypaste the MultiTimer class from gamelib to give each decal a decaying time, and then remove them when the time has passed.

Thanks for the reply Metatron. How do I remove the decal when the time passes. I make a call to FreeEntity when the set time expires, but that doesn't remove the decal.

are you setting the parent of the decal? if so then it should remove the decal automatically when you free the parent entity.

I am setting the parent of the entity, but I'm not removing the parent until the user quits and I need the decal to disappear before then since these particular decals are bullet holes.

ah sorry... when you said the decal's entity in the first post i thought you meant the pick entity that it was being attached to... not the decal itself.

 

I would suggest that you post your code because i can free a decal just fine... i assume it has something to do with however you are creating an array of them...

Here is my code for creating a decal.

Decal = CreateDecal(pick.surface, TFormPoint(Vec3(pick.X,pick.Y,pick.Z), NULL, pick.entity), 1.0f, 0);
EntityParent(Decal, pick.entity);
PaintEntity(Decal, LoadMaterial("abstract::dev_decal.mat"));
UpdateMesh(Decal);
AddMesh(Decal, pick.entity);
time = AppTime();
sprintf(key, "%f", time+5000);
SetEntityKey(Decal, "killtime", key);
SetEntityCallback(Decal, (byte *)UpdateBulletDecalCallback, ENTITYCALLBACK_UPDATEPHYSICS);

 

And here is the code for freeing the decal once the specified time has been reached.

void __stdcall UpdateBulletDecalCallback(TEntity entity)
{
float time, time_value;
str key_value;

key_value = GetEntityKey(entity, "killtime");

time_value = flt(atof(key_value));

time=AppTime();

if(time>time_value)
	FreeEntity(entity);
}
