Point In Front of SpaceShip

Say I have a spaceship with it's pitch,yaw,roll being constantly adjusted, and my goal is to put a object infront of the ship say 10000 units away - what are the sin/cos code portions to do this - or is there another way? Teff |

put a object infront of the ship say 10000 units away Well, I'll try this way: 1) create the object parented to the ship; in this way, it will be at 0,0,0 related to the ship, and 'oriented' as the ship: cube = createcube(myship) 2) unparent the object with: SetEntityParent cube,0 3) move the object 10000 units far away with: MoveEntity cube, 0,0,10000 Note: if you need to move the object so that it stays always in front of the ship when the ship moves, you may not need the unparent bit. Hope this has sense for you, Sergio. |

TFormPoint 0, 0, 1, Ship, 0 X# = TFormedX() Y# = TFormedY() Z# = TFormedZ() That will tell you the position in global space of a point 1 unit in front of your ship in ship space. If your ship is scaled down by 50%, ie, 0.5, then you'll have to increase that distance to compensate, by the opposite amount. 1.0/Scale#, which in this case would be 2. |

i beleive all u need: thinginfront=createpivot(plane) moveentity thinginfront,0,0,distance |

I tried sswift's example and it worked exactly after refering to the help! --and the pivot is also a good solution Thanks Teff |
