the car is way too fast. it's moving with 1200 m/s WHAT??? there's no piece left everything bursts into every direction. that doesn't look like a crash it's more of an explosion of 1000 pieces
i made a very similar rocket that works on water, too. But it hasn't got much thrust like yours. but you can increase it by adding a geometry above your water spawner with a very high negative attraction. with this you can theoretical increase your thrust infinitely high. i used this principe here
nice. i noticed you're starting to script now. now i know why you were asking for a constant attraction
yesterday i decided to use thrust vectoring for the javelin, too because the other thing didn't work very well. but it will be a lot of work because i will use 100% scripting.
Acceleration doesn't work... Look at this. There are bugs, too, but it works perfect if you run the simulation at 10% speed. Would be very cool if you find a way to calculate the acceleration at 100% simspeed.
(Btw: I made a new formula which is way more simple but I didn't update the scene. Still the same problem though )
cool. but you could make scene.my.dir1 and scene.my.dir2 variables depending on the distance between mouse and pen. so the motor will slow down and stops when the mouse and the pen are at the same position. so there's no wiggle.
