Basically what we’re doing is asking the following:ġ) Is there a collision one pixel in the direction that I am moving (up/down)?Ģa) If no, move one pixel in that direction (up/down).Ģb) If yes, rest your speed (up/down) and exit the loop. I’ll quickly walk you through the loop in normal speak. If (!place_meeting(x + sign(vx), y, oParSolid)) If (!place_meeting(x, y + sign(vy), oParSolid)) I will also use vx and vy to describe the horizontal and vertical velocities of the player object. Basically, the player should stop when making contact with the floor, ceiling, and walls.įor these examples I will be using Game Maker syntax and function calls (I am comfortable in this environment and most of my followers expect this). From there the concepts involved can be expanded rather easily into jump through platforms, moving terrain, etc.ġ) The first step is collision against solid, flat block objects. However, I understand that it isn’t exactly intuitive to a lot of people. Well honestly, I’d consider that to be simple collision detection. How do I implement slopes of different angles and other more advanced collision features? I get this question almost every day, so it’s about time that I talk about it. I’m going to start by taking requests for blog posts, and if interest continues, I’ll invest some time into a video series! I have been asked time and time again to start doing video tutorials for Game Maker Studio and programming concepts in general.
