I create a 2D shooter on Libgdx. There is a sprite of a spaceship and a shell. It is necessary to do so that when the textures of the ship and the projectile intersect, then ... the ship's health decreases, let's say. But at the same time that the collisions were strictly along the contour of the textures. Maybe in libgdx there is some sort of class for creating exact collisions? Tell me.
