Dont u guys said "We arent coding movable solids. too hard" i just noticed that the bubbles from soap are kind of moveable solid (While on low pressure!) So what about just coding the blubble element to the "Special" section changing its color (idk, maybe brick-like?) itd be not destructable by just crashing. and just had a higher "Friction" with background so it moves slower CONGRATS! you coded movable solids! not exactly, but may do the job. my pressurizer is waiting to launch a rocket!
