Hi guys/girls .Been a while since i posted on here. I am currently making a 2d platformer. I want to use physics to show the effect of explosions and such…However i cannot get add force or add impulse to work . This is my first real attempt at creating a full 2d game .Do i need paid plugins.Does unreal have a 2d physics engine and .More importantly can the 3d physics engine be used in 2 dimensions?? Thanks guys /gals Using unreal 4.23.
