    So I need help with Tile collision I'm using Shaun Spalding's Tile collision code (since I'm not good at coding) and I have physics on for jumping and falling but my character is falling through the floor PS horizontal collision is working and this is my code for step

    var bbox_side;

    key_right = keyboard_check(vk_right);
    key_left = keyboard_check(vk_left);

    hsp = (key_right - key_left) * 4;


    //Horizontal Collision
    if (hsp > 0) bbox_side = bbox_right; else bbox_side = bbox_left;
    if (tilemap_get_at_pixel(tilemap,bbox_side+hsp,bbox_top) != 0) || (tilemap_get_at_pixel(tilemap,bbox_side+hsp,bbox_bottom) != 0)
    {
    if (hsp > 0) x = x - (x mod 32) + 31 - (bbox_right - x);
    else x = x - (x mod 32) - (bbox_left - x);
    hsp = 0;
    }
    x += hsp;
    //Vertical Collision
    if (vsp > 0) bbox_side = bbox_bottom; else bbox_side = bbox_top;
    if (tilemap_get_at_pixel(tilemap,bbox_left,bbox_side+vsp) != 0) || (tilemap_get_at_pixel(tilemap,bbox_right,bbox_side+vsp) != 0)
    {
    if (vsp > 0) y = y - (y mod 32) + 31 - (bbox_bottom - y);
    else y = y - (y mod 32) - (bbox_top - y);
    vsp = 0;
    }
    y += vsp;

    Why are you using physics? It's incompatible with your collision code.
