Hello cgd82
I’m actually not sure why I didn’t think about this before but when taking another look at the original question, you can fix his problem of too much momentum by simply changing one of the float values inside of the Projectile’s blueprint. As part of the calculation for the amount of impulse to add, it multiplies the current velocity by 100 by default. After changing the speed of the projectile to 20000 as the user did, any cubes that were shot would go flying. I changed the equation to only multiply the velocity by 10 and it’s moving the cube as much as it did initially.
Speaking of which, this also negates my previous post because that is almost exactly what these projectiles do. They never actually exert force on the object they hit by simple collision, they just add impulse as part of their collision response. This also explains why changing the mass wasn’t making a difference, since it was only going off the velocity.
