Need Help with MonsterAI script

[poison7797]

Hello, im having trouble releasing dead enemy after some time.

When i kill enemy i want body to disappear after 5 sec.

I have change AI script , have no errors but it does not work.

Can someone help ?

 

Here is my code.

 

Thanks

Your EndDeath()-Function only gets called once, after the dying-animation is finnished. Assuming, you want the timer to start then, you should replace

self.removeBodyTimer = self.removeBodyTimer + (Time:GetSpeed()/100)

at that point by

self.removeBodyTimer = 0

 

Then you have to increase the timer every frame and check, if its value exceeded the given threshold. So, you should move the line, you originally had into UpdatePhysics()-Function.

You should have a chunk there that says:

if mode == "dead" then
   self.removeBodyTimer = self.removeBodyTimer + (Time:GetSpeed()/100)
   if (self.removeBodyTimer > self.removeBodyTime) then
       self.entity:Release()
   end
end

Thanks for help. I done that but still wont work!

Can you check ?

Thanks

[Ma-Shell]

It has to be "self.mode" inside the UpdatePhysics()-Function (My bad )

If it still doesn't work, try printing the value of "self.removeBodyTimer" after increasing it and see, if this creates any usable information.

[poison7797]

Thanks, still wont work. System Print wont print anything.

I have create RemoveBody.lua and when i put that script on some entity, lets say barrel, its working.

But when inside of MonsterAI.lua it just wont work.

Strange...

[Ma-Shell]

You put the chunk inside the

if self.mode == "attack"

Block.

This is bound to fail. Move it outside.

[poison7797]

outside where ? I have put that code on many places inside UpdatePhisics.

Can you give me example! Please!

[poison7797]

Ohh i did it

Thanks a LOT MAN!!!!!
