Is there a way to create a bullet that goes faster the longer it exists? I tried doing negative air resistance first, but that didn't work. Would there be another way to do this besides using a mass-emitting AEmitter attached to an MOSRotating? |

With lua, sure. Or AEmitters. Code: function Update(self) self.vel = self.vel * 1.001 end |

If I recall correctly particles disappear if they are flying faster than some arbitrary value (500 comes to mind, but I am not sure), so you'd probably also want to add a check for that before changing velocity further. |

Also, Lua scripts run per frame, and since the FPS can fluctuate while in-game time remains the same (or vice versa), that script will accelerate your particle at different rates based on FPS, and won't be consistent with the in-game time. |

Do yall know if this script works with MOSRotatings? I'm doing this with an autocannon-based weapon, adding it to the round causes a could not match property error, and adding it to the MOSRotating does nothing, no matter how high the value. |

In the script, it needs to be "Vel", not "vel". Capital "V". Attaching it to the MOSRotating should work fine. |

You could multiply by delta time if that's possible, I don't really remember. edit: Seems like you can only find the fixed delta time that the game tries to run simulation at. Oh well |

You can have a timer to check the exact amount of time elapsed since the last frame. |
