| Hi, I'm having trouble using the EntityParent command with my Types. I have 2 types defined :- Type planet Field olddist Field entity Field scale End Type Type bullet Field entity Field stage Field speed End Type And I have template sprite for the bullets:- flare=LoadSprite("bullet.bmp",3) When I hit the Mouse button, I create a new bullet type:- If MouseHit(1) And mult=0 Then ship.bullet=New bullet ship\entity=CopyEntity(flare) ship\stage=1 EntityType ship\entity,BULLET_COL EntityRadius ship\entity,5 PositionEntity ship\entity,EntityX(cam),EntityY(cam),EntityZ(cam) RotateEntity ship\entity,EntityPitch(cam),EntityYaw(cam),EntityRoll(cam) ship\speed=acc+30 End If Pretty Straight forward so far. When the bullet hits a planet though I want to attatch the bullet to the planet so that my "explosion" rotates with the planets rotation. My collision code looks like this:- For ship.bullet=Each bullet If ship\stage=1 Then MoveEntity ship\entity,0,0,ship\speed hit=EntityCollided (ship\entity,PLANET_COL) If hit Then ship\stage=2 ship\speed=1 EntityParent ship\entity,hit,1 ElseIf EntityDistance(ship\entity,cam)>40000 Then ship\stage=4 End If End If If ship\stage=2 Then ship\speed=ship\speed+1 ScaleSprite ship\entity,ship\speed,ship\speed If ship\speed=200 Then ship\stage=3 End If If ship\stage=3 Then ship\speed=ship\speed-1 ScaleSprite ship\entity,ship\speed,ship\speed If ship\speed=0 Then ship\stage=4 End If If ship\stage=4 Then FreeEntity ship\entity Delete ship End If Next Stage 1:- Checks for A Planet Collision or Distance. Variable "hit" contains the handle of the planet. EntityParent then assigns hit as the bullet parent. Stage 2:- Uses the bullet speed field as a sprite scale variable as the bullet is now stationary. When it gets to the ScaleSprite command I get an "Entity Does Not Exist error!" When I omit the EntityParent command everything works fine, I just don't get the rotation with the planet. Can anybody plaese explain why the EntityParent command is removing my sprite entity? Sorry about my post...How do u add those pretty code boxes? :-) Thanks Phil. |

| Never mind. The problem seems to be in my LOD function. When the planets were further away I was swapping them for lower quality spheres for speed. Somewhere in the process the entity handles must be getting screwed up. I Will stick to fixed planets for now and tackle the LOD again when my brain has recovered. Now for constant game speed !!!! YIPPEE this is fun !!! Phil. P.S. I'd still like to know how to put code in the boxes in the forum please. |

Certainly its [ code ] 'your code here' followed by [ / code ]leave the spaces out though. |
