Entities parent

| Is there a way to determine an entities parent? What I am doing is creating my own custom partical system, and I am attaching emitters to entities, but i need to know when the entity has been destroyed/freed so that the emitter can detroy itself at the time the parent is destroyed. |

| GetParent() |

| Cool, thanks. However if the parent has been removed then this command still causes the program to crash with entity does not exist. Think I have a workaround though. I can make a global pivot called Trashcan, when say a rocket with an emiiter attached to it explodes, i can cycle through its children and reparent them to trashcan, now in the emitter loop if the parent is trashcan then delete the emitter properly. If you know of a better way please let me know. Thanks |

First - why don't you use the entity the emitter is attached to as the parent. Second just use getParent()if getparent(particle)=0 freeentity particle |

| well it seems that if you set a parent to an entity, then free the parent.. Getparent will still report the same entity as the parent even though it does not exist anymore. Example: Graphics3D 640,480,16 CUBE1=CreateCube() CUBE2=CreateCube() While Not KeyDown(1) If KeyHit(2) Then EntityParent CUBE1,CUBE2 If KeyHit(3) Then EntityParent CUBE1,0 If KeyHit(4) Then FreeEntity CUBE2 If KeyHit(5) Then CUBE2=CreateCube() UpdateWorld() RenderWorld() Cls Text 10,10,"CUBE1 PARENT "+ GetParent(CUBE1) Text 10,60,"CUBE2 PARENT "+ GetParent(CUBE2) Flip Wend |
