Thruster sprite (help asked)

| Hi, I am trying to get life into my space ship. The space itself is modelled and textured. I want to have a number of sprites "firing" my thruster. See one example picture of the thruster animation here:  I want to fly around the space ship while the thruster keeps burning in the direction (i.e. the sprite must turn as my camera turns). How do I apply / pivot the thruster picture to the space ship engine ? Are there any tutorials or examples showing a sequence of thruster pics mounted on a space ship engine while the camera is flying around ? Thansk for help ! Bernd |

| One comment: Since I will have dozens of ships in the space game, there is no chance for extensive particle engines. So, I choose sprites as base for the thruster pics. Is this the correct decision ? Thanks, Bernd |

| Hum, I don't know if I've really got what you are saying, correct me if I'm wrong: You want to use a 3D sprite for the thruster effect; that sprite should be in some way located behind the ship, so to give the impression that the ship has a flame behind. That flame - which should be a 3D sprite - should be rotated accordingly with the ship rotation (not really clear what you mean with the camera here). If this is right, you need a couple of things: - parent a pivot to the ship, so that when the ship moves, the pivot moves accordingly - put the sprite thrust at the pivot coordinates - rotate the sprite accordingly with the ship degrees, using RotateSprite command. Anyway, in my opinion, using a particle system would make the whole thing much more realistic in a 3D world, rather than a static sprite which rotates.. Hope it has sense for you, Sergio. |

| Parent the Sprite to a pivot which is at the thruster position and change the "SpriteViewMode" so that the sprite can move independently to the camera... |

| Do you have any example BB source for me that explains / shows a particle thruster that is mounted onto the ships back ? Thanks, Bernd |

| Do you have any example BB source for me that explains / shows a particle thruster that is mounted onto the ships back ? Hi Bernd, you have it already. If you take a look in the B3D examples folder from your B3D installation directory, some of that sample could already help you. Have a look also in the code archive, which I consider a rather good mine gold. Sergio. |

| Check the Galactic source code for a simple, "particle exhaust/thrusters" system. This system creates jets of varying colour and length and transparency relative to speed/engine size. The jets create a trail, leaving an arc if the craft banks/dives etc. ________________________________________ EDIT- changing the spriteviewmode may not be a great idea in this instance, depending on how your spacecraft moves in relation to the camera... |
