True realistic cannon ammo does not use thrusters, for that is a rocket propelled grenade. Almost all of the speed comes from the thrusters. Try things like making the motored circles have infinite friction and no bounce. But good job for not making this thing terrible!
So. As far as I know this is not a Roblox meme, unless I have not been with the community for long enough. Also, someone else made the explosive button, Unless they don't care about credit, please write the names of users you have used things from in the details, thus crediting them. Good day.
When geometry actions make a terrifying shape from the depths of a bad place. Would go good in a Algodoo horror game monster. (this comment is not meant to be an insult.)
To answer the elephant in the room on the scene instead of your actual question:
In nearly all engines, going out too far from the origin point will cause physics and a variety of other things to break. In Algodoo's case, let's say that you throw something downwards with no aerodynamics really, really hard, and enable camera follow on the object, and wait for it to magically disappear. First of all, when you try to create an object (creating a polygon won't work and creating a chain crashes Algodoo), you will find that you will need to make the object very big in order to place it. Second of all, when you try to zoom in or out, the camera will eratically shake up and down. Third of all, gravity is very weird and I reccomend setting it to 30 strength so you only wait a third as long to see stuff fall.
You're very amibitous, this track is quite big, hope ya didn't steal it
I don't see the point of the "win with 1 character" achievements considering that all the axles & controller settings on all the cars are the same
