Love the video so far. I noticed that the barrels are more stable with the new collision but they jump when the game starts. I solved that by unchecking the option “Start Awake”. But the barrels are still very unstable when hit by the projectile. I put the barrels in a pyramid shape. Even if I hit the top barrel, all the barrels jump, and fall. I changed the mass for the barrels to 25,000, but that seems like a lot. Is that because the projectile is traveling at such a high speed (4000)?
