hey guys i need help,im making a 2d procedurally generated sidescroller game and i want my “world” to be created from the lowest point of the camera to the highest point of the camera divided by 0.64 units cubed tiles and when i try Camera.main.Rect and use the minX to get the lowest point i get 0 and it shouldnt give me 0 because it is not 0…can anyone help with that please?
WHAT IT DOES:
it loops on i as the index for horizontal block
j is the index for vertical block
the place to start the generation of blocks is supposed to be from the camera’s lowest y point. the blocks are 0.64 units each but something was wrong with my calculation and it was rendered better if i calculated the space between each block as index times 0.62+offset that i tried getting and if i were to to index times 0.64 it would render it with black lines between my sprites… if theres a fix for that too id really appreciate that.
thank you for the solvers
