Assault cannon, artillery and railgun projectiles don't respect conservation of momentum
Due to an erronious setting in the weapon definitions these weapons are capped at a max speed which is equal to their launch speed so if you are travelling forward they will still only launch at their launch speed.
In the demonstration video the launching ship is flying at 475 m/s which is 25 m/s below the assault cannons launch speed what we would expect to get here is the projectile flying at 975 m/s instead of the actual 500 the demonstration video uses a speed mod to make this effect more visible.
Reproduction:
build any test rig that can move and accelerate it up to some speed shoot forward and observe as the projectile only flies at its launch speed rather than launch speed + grid speed
Fix:
Just increase the max speeds of the affected projectiles by a lot and because they dont accelerate their behaviour should remain normal
I have the same bug
Hello engineer,
Thank you for writing to us and providing the video.
The issue seems to be related to the MOD that's being used, as it doesn't occur in the vanilla world. When you fire projectiles from full-speed grids in the vanilla game, you do not collide with your projectiles.
If your MOD pushes the grids to max speed, it should also increase the projectile speed accordingly. If you have created this MOD, please review it. If you're using someone else's MOD, please contact the MOD creator to address this issue.
Please note that we don't provide support for MODs. It's the MOD creator's responsibility to maintain their MOD and ensure compatibility with the latest version of the game.
Since no further support is required from our side, we will be closing this thread for now. If you experience any other issues, please feel free to reach out to us again.
