Hi, In my platform game I am using hspeed to move my character in order to utilize friction (I want the character to slide a little when they stop moving). This works fine however when I try colliding with wall objects from the side, the character sticks to the wall a little. My guess is that this has something to do with the event when colliding with the wall object. The code for that event is here:

move_contact_solid(direction,12);
vspeed = 0;

Please let me know what I'm doing wrong/How to fix it.

Yes a very advanced problem...* You're getting stuck in the wall because you are going fast enough to intersect with the wall before the collision is detected. THere a numerous approachs to solving this and I think you'd benefit from searching the tutorials forum for a Platformer example or two. There are some very good ones and a decent example could potentially help you with other common problems like this.

Instead of the collision event, place this in the step event:

if !place_free(x+vspeed,y)
 {move_contact_solid(direction,speed)
 hspeed=0};

This should solve it.

Why not create your own speed variables if hspeed gives you problems? It is totally possible to make custom friction (e.g. very easy)

xSpeed *= 0.95;

This should solve it.

This causes the character to fall through the ground.

Is the ground a solid object?

Is the ground a solid object?

Yes.

Try changing the "speed" to hspeed.

Sorry for the several-week bump, but I had this problem, too. Reading this thread helped me figure it out. Just make two of those events: one for vertical, one for horizontal.

if !place_free(x+hspeed,y)
{
    move_contact_solid(direction,speed) ;
    hspeed=0;
}

if !place_free(x,y+vspeed)
{
    move_contact_solid(direction,speed) ;
    vspeed=0;
}
