I am creating a game that generates random landscapes that the character drives along. There are 7 "sections" right now, and there will probably be 25 or so total. For example, one section is a hill, one is a ramp, etc. I am loading these images and physics bodies (whch are made with Physics Editor) when the character passes halfway between the previous section. The previous section is also destroyed. There is a frame rate skip when this function is called because it is loading these images and physics bodies during the gameplay. How would I preload these images and physics bodies before the the user starts playing? Thanks!
