    GameMaker Detect multiple collision points on one object

    (very new to game maker and programming languages in general) I have a particle system that trails behind the players character (which is a cube) by detecting when they are on the ground and spawning the particles at the right most side of the block. However, this has the side effect of when the...

    Collision problem - objects going through objects they should stop at

    I'm fairly new to GameMaker so I may not fully understand some concepts. In the game I'm making, furniture flies around to hit the player. At the moment, it mostly doesn't stop when it hits the player (occasionally the collisions work, it's sporadic), which it should, and goes through the...

    SOLVED Collision For Right And Down Movements 1 Pixel Off.

    Hey so I'm using a tile based collision system, but for some reason collisions for right and down collisions are one pixel off, stopping one pixel before the solid tiles, but it works just fine for the left and up collisions, always stopping when it collides with the walls, does anyone know...

    GameMaker How to properly make the object move down?

    I have this tile object where if it activates and of a certain type, it will burn down the tile below it. However, at certain circumstances, it will appear to float on the burned down tile and the burned down tile's text outline looks transparent. The collision code is preventing it from...

    Game Maker 1.4 - Collision Detection Not Accurate

    Hiya! I am using Game Maker 1.4. I am having troubles getting accurate collision detection with my obj_player and my obj_fire_hydrant. I am modifying the collision shapes to be only specific areas of both objects, but when I run the game, the parameters I set are ignored; it's as if the...

    SOLVED collision_line algorithm different from draw_line?

    I can't pinpoint what I'm doing wrong. The concept is a rectangular object navigating slopes (collision line). Im using draw_line to debug, but it "looks" like the collision line is off by just a few pixels, which is enough to throw off the whole system, but only in a certain quadrant. I'm...

    GameMaker Collision Event + place_meeting [SOLVED]

    Hello everyone! The problem I have faced with is more or less common, but I didn't find any solutions for my case. I create bullet object and it has a speed. As far as I know, the speed determines the distance in pixels where object would be drown every step. So if the bullet has speed 6, and...

    Legacy GM Collision Detection Not Working

    I'm trying to convert the collision detection that prevents the player from falling through the floor into code. Originally, I had it set as a collision event with the collision object that would set vspeed to 0, and move to contact with said object (to prevent this issue I got with the player...

    Discussion Collision differences in runtime 2.1.3.189 vs recent runtime updates

    I saw that some people were having collision problems also with the latest runtime updates. Was that just with objects that use physics? My game doesn't and my collisions are broken too. This is my player character jumping and colliding with the invisible wall objects in the older Runtime...

    Legacy GM Check for collision between two other objects

    Hello. Is it possible to have an object check for collision between two other objects and have that collision affect itself? The way how I'd use it is simple. I have a camera object that snaps to the player's position based on an 800x608 grid. I want it to pause any movement when the player is...

    GML Problem with HeartBeast's Tile Collision System

    Hi, I've been having a small issue with (I think) HeartBeast's tile collision system in a 2D platformer environment, and I think I've found the place where it consistently fails, but I'd like some confirmation from someone a little more experienced than I am. The jist of it is that I've...

    So, I'm working on a platformer that will use hybrid tile and object collision for floors and walls.
