This is the FASTEST Physics engine I've ever made ( and maybe might be among the fastest on scratch ) [ still wip. Expect bugs ] ⭐Controls⭐ "c" to spawn circle at mouse "r" to spawn rectangle '''' "p" to spawn polygon '''' "s" to spawn star '''' Supports collisions between circles and polygons and is highly optimized. It also allows you to combine different primitives to make a shape. Eg. cube , circle [ Press "s" as an example ] Has spring constraints ( still working on it.. )
