I’d like to have physics on my character so that if another actor with physics bumps into it, my character will move. (Or push it down when in a water volume).
I set “Enable Physics interaction” to true, and I can push other objects, but the other objects can’t push me.
If I set “enable physics simulation” on my character root component, I won’t be able to move it anymore.
Am I missing something ?
AFAIK, you can’t apply physics impulses to characters the same way you might do it for a crate. Are you using a “Character” pawn? They have a “LaunchCharacter” function that might do what you want.
Yes I am using a ACharacter pawn, using LaunchCharacter would be weird I think ? I could use this with onComponentHit but then the Actor that bumped into my character will stop moving.
I spent some time researching how to apply an impulse to a character, and LaunchCharacter was the best thing I found on the internet 
I use it when my character gets hit by projectiles, for example.
