GML Throwing knife in wall

[Distorted]

so this might be a bit specific but I'm working on a game that involves throwing knifes.

once a knife is in the wall the speed goes to 0 and I want it to be stuck there.

only because of the speed of the knifes most of the times they get stuck in the middle or even stick out the other side of the wall object.

I've been brainstorming on this for a couple hours now, can somebody help me?

Well it seems like you're just throwing knives at the wall and hoping they stick.

Bad joke.

I would suggest sharing your code so we can see what could be causing those results.

I can suggest that you look into pixel perfect collision.

if (place_meeting(x+1,y,obj_solid)) or collision_line(xprevious,yprevious,x,y,obj_solid.x+1,0,1)
{
move_towards_point(obj_player1.x+300,obj_player1.y,0)
x = xprevious
y = yprevious
}

if (place_meeting(x-1,y,obj_solid)) or collision_line(xprevious,yprevious,x,y,obj_solid.x-1,0,1)
{
move_towards_point(obj_player1.x+300,obj_player1.y,0)
x = xprevious
y = yprevious
}
kind of embarrassed to show this tbh

Have you tried putting this in the End Step event?

Also, nothing to be embarrased about.

I have no idea why but now they're all getting stuck before hitting the wall and for some reason when I shoot them trough a wall to the right it passes trough and then stops.

you need pixel perfect collision

instead of moving knife the 'speed' amount of pixels per frame like x+ = 10

you need

repeat(knife speed amount of times)
{
        x += 1;
        if (collision with the wall)
                break; //break the loop
}

thanks! I believe I've already fixed the problem, but I'll keep this in mind
