Delete an entity

| Hi! I've got a problem when I want to delete an entity. Function DELETE_ENTITY() If KeyHit(57) Then For mesh.meshinfo=Each meshinfo If picked=mesh\mesh FreeEntity mesh\mesh EndIf Next EndIf End Function The DELETE_ENTITY function works but after I call an other function to pick an entity and aplly an alpha on it. Function PICK_ENTITY() If MouseDown(1) And mouseInView() Then picked = CameraPick (camera, mxp, myp) If picked CameraProject camera, EntityX (picked, 1), EntityY (picked, 1), EntityZ (picked, 1) PositionEntity Gizmo, EntityX(picked), EntityY(picked), EntityZ(picked) EntityParent picked, 0 EndIf EndIf For mesh.meshinfo = Each meshinfo If mesh\mesh=picked EntityAlpha mesh\mesh, 0.8 Else EntityAlpha mesh\mesh,1 EndIf Next End Function I've got an error message!!! In fact, it's in the next lines that there is a problem. For mesh.meshinfo = Each meshinfo If mesh\mesh=picked EntityAlpha mesh\mesh, 0.8 Else EntityAlpha mesh\mesh,1 EndIf Next I think that the program want to apply an alpha on an entity deleted and I don't know how to do |

| Function DELETE_ENTITY() If KeyHit(57) Then For mesh.meshinfo=Each meshinfo If picked=mesh\mesh FreeEntity mesh\mesh delete mesh EndIf Next EndIf End Function your not deleting the type's instance 'delete mesh', or if you required to keep all types then you will need to set the mesh's pointer to zero then once you have freed it. do a check mesh mesh\mesh>0 to check you have a vaid pointer to your meshs. |

| Oh thank you very much Kev, It woks fine! I never notice that function (delete) before!!! |

| Yep, FreeEntity just clears the actual entity's internal information. After you free it, you still have the type object, and your trying to apply EntityAlpha to an entity that was deleted. By using 'delete' the type object won't come up when you scroll through them all (for...each), so it won't try to set the EntityAlpha to an entity that no longer exists. |
