how to add radial force effect around character when i press mouse button? all physical objects around due to fly out to the sides. Can some one help me how i do this at blueprints? thx
I think you can do that with Radial Force Component and a particle effect for the visuals.
This is correct, you can have a Radial Force Component that waits to trigger until a Fire Impulse node is executed. In the component you can set the strength of the various forces.
Do I need this component on my character or the thing emitting the force? And do I need to set my character to simulate physics? Because when I set simulate physics on my capsule component it goes nuts. 
It would go on the character. The objects you want affected by radial force will need simulate physics
