Variable Length Jumps | Coding a 2D Game Engine in Java #50 смотреть онлайн

In this episode I go over a method to create variable length jumps. This method involves counting a certain number of frames, and after enough frames have passed ignoring the player input if they are pressing space. If they stop pressing space early, then we stop applying a jump force. I also scale the jump force linearly so that it runs smoothly and you get the same jump every time if you supply the same input. Next, I go over how to make a block "bop" when Mario hits the bottom of it. I extend this same concept to question blocks, and finally I implement a question block that spits out a coin when Mario hits it.
