Trying to use all kinds of nodes like radial force and impulse but I don’t think I’m close to setting it up right.
Use the add impulse node. Use a very large value.
You can get as reference the First Person Template, there is a FirstPersonProjectile blueprint which does the trick: AddImpulseAtLocation getting the Location of the projectile and its velocity.
If you are not using projectiles and getting the hit result under cursor, the trick is the same, apply the Impulse at the hit location with the impulse force desired.
