XNA - continuous obstacles accross the screen
Im in the process of making a frogger style game, xna is brand new to be, ive a basic map with a movable character, i guess the next stage is to have obstacles / cars continuously streaming across the screen. but ive no idea where to begin.
i know how to get a car across the screen once the game begins, but once it leaves the screen should i have it immediately return to the other side and loop, or have some sort of random number to wait and then repeat the process.
any advice / bits of code / or ideas of code i should explore are more than welcome. thank you.
