This is the 20th video in a series on remaking Hotline Miami in GameMaker Studio.
The video tutorial shows you how to setup a limted but very easy to implement collision system which works effective in this project. We simply have to check if there is an object collision with any obj_wall instances and if there is none, horizontal/vertical movement is possible.
This system has 2 limitations. No decimals are allowed (and no acceleration also) plus the start placement should be on grid (so no decimal numbers as a start placement also).
Note: Decimals can be used in an advanced version where you have rounded values with extra checks but this is kept simple so here these 2 limitations are fixed.
