If you like this guide feel free to add suggestions for my next one ♥️

This guide is both assuming your know the bare basics of gamemaker and or just looking for a quick easy to somewhat read guide!

if you know the basics of gamemaker (creating objects, room layers, scripts ect) skip to the CODE section :3

if your new to gamemaker I highly recommend you type the code rather then copy paste
it helps more then you think

For this guide I am going to use my topdown movement player controller
If you want to use it I have a guide right here!


For this guide we only need the one object which I'll be calling oSolid!
you might be using objSolid or obj_Solid or even o_Solid! These are all fine!

To create your object, Go to your asset browser (by default should be on the far right of the window)

right click on the objects folder, Hover over create which should expand out a bunch of options. Then find and click object (at time of writing it should be the 5th option).
I'll be naming it oSolid feel free to do the same!


repeat the previous actions but with sprites, Feel free to name it whatever you'd like but I'll be naming mine sSolid

To create a tileset, Go to your asset browser, right click and hover create.
Now create a new Sprite AND Tile Set

Now draw or import your tiles in your new sprite which I've named sTiles

My sprite looks something like this


Now select the sprite in your Tile Set and change your proprieties to fit your tile size & spacing!

My Tile Set looks like this

Head over to your room and in your layers.

now find and create a new tile layer!
I will be naming mine "Collision" but feel free to name it whatever you like!



now setup your room with tiles spread around as well as your oSolid object!

before we get started make sure to create a new script!

I'll be calling mine player_collision

as of version 2023.8 we can take advantage of the new collision system feature and use a tileset for any static scenery!

And as of a recent change to GameMakers collision system, they now accept an array of object or instance ids! using these new changes we can write this:
if you'd like to learn how place_meeting() works, Check out the gamemaker docs[manual.gamemaker.io]

The reason why we provide an array here, is that oSolid is one of our collidable objects! We can add any object, instance or tile layer in this array!


this will check if your current x position + the amount your adding will collide!
If true then set your movement to zero!


make sure you place this function above the code that changes the x/y

what my code looks like


and hit play! if everything is correct you should now be colliding with your tileset and solid objects! :)

and were already done!! :0
You did it! ♥️

Thanks for reading! I hope this helped you in some way or form :3
I'm no teacher but seeing there was no proper guides I knew I had to try!
