So i$\text{'}$m working on a $2$D game so far I have gotta the screen size from camera, gotten the size of my sprite and made the sprite go off in a direction at a certain speed how do I now work with collisions using those values, check for collision with the wall in Update Respond to collisions by $(1)$moving the entity out of the wall and $(2)$ changing the velocity as discussed in the video above. I$\text{'}$m not sure what to code is it my sprites postion and then the walls position what does that look like?
