    GMS 2.3+ [SOLVED] simple collision with rotated sprite not working

    Hello, surprisingly I didn't find the question already asked here in the forum: why is an instance running one pixel into a wall to its left when it rotated around 180° ? The sprite is 16x16 pixels, the origin is the middle center and its collision is set to be precise. the movement code is...

    Don't know fixing collision. It always stuck.

    everytime the rectangle hit the ball in the left or the right side, the ball stuck and the score goes up rapidly. Is there any tips to fix this problem? Video:

    Collision script won't run

    Hey everyone, I'm trying to create a normal state so that I can switch between other states, but to do that I decided I needed to make a normal script which contains a script for player input and collisions. However, when I tried to make a script for the collision block of code I get this...

    noob question, object properties.

    so i was wondering, how to assign "properties" to objects. what i mean by that: for example, i have Player, who is colliding only with obj_solid. So, to add different kinds of solid platforms, i create an object as a child for obj_solid, so that player will collide with all of them. but that is...

    SOLVED How to lock x value to actual or lesser?

    I'm trying to make a object freeze it's positive x so it can slide walls on collision. Basically i have this check: if (!place_free(x + collisionOffset, y)) { } collisionOffset is a variable to determine how far the object will be from the collision point on the given coordinate (x+, x-...

    How could I fix this so that it would detect enemies at the path of the projectile and not where the projectile is actually existing.

    As far as I can tell, the below code works. The only issue that I've noticed so far is that the collision line detection isn't working. The collision detection wont happen in-between the projectile therefore leaving enemies unaffected that should of been affected. I have fast projectiles and the...

    Hi, I'm making a 2d platformer game, and i have different objects for walls, floors and boxes. I was wondering if i have to rewrite everything i did for walls and change the oWall to oBox, or is there an easier way to do that? Here's the code I used to make the player stop if they collide with...

    GMS 2.3+ oneway platforms that are also slopes

    So I have been fiddling with this for a while now, trying to adapt my spaghetti code to allow oneway platforms that are also slopes. I am quite new to coding in general but I do have slopes and oneway platforms working properly in my side-scrolling platformer, however, my oneway platforms that...

    GMS 2.3+ Collision Issue, but only when moving Left and Up

    I found a script for collisions that works when colliding with the ground, or walls to the right. I am trying to figure out how it ticks, but there is a problem I can't fix. It gets the player stuck in ceilings and walls to the left. I am pretty confident the issue is here: if...

    I've started work on a top-down, action rpg of sorts. I'm using Shaun's platformer code as a base until I finish watching his tutorial on action rpgs. I have the code set up for horizontal and vertical collisions and those work just fine. However, I have set up a sprint/dodge key that increases...
