Game Maker Jump Through Moving Platforms Code - Rexfurry

Jump through code (can either go in Step Event of idle or moving Jump Through Platform)

if obj_player.bbox_bottom > bbox_top {solid=false}else{solid=true} //Checks for player and determines if solid or not

Create Event of Moving Jump Through Platform:

hspeed = 1

Collision with collision object in Moving Jump Through Platform:

hspeed = 1

Collision with idle or Moving Jump Through Platform object in Player:

if other.solid=true{move_contact_solid(direction,12) vspeed=0}

Step Event of Player:
//Optional Movement/Gravity System
/*
if place_free(x,y+1){gravity=0.7 gravity_direction=270}else{gravity=0 gravity_direction=270} //Gravity
if place_free(x-4,y)&& keyboard_check(vk_left) //Move Left
{
x-=4
}
if place_free(x+4,y)&& keyboard_check(vk_right) //Move Right
{
x+=4
}
if keyboard_check_pressed(vk_up) //Bad Jumping System For Tutorial/Testing Purposes Only
{
vspeed-=12
}

//Moving Platform Code
if place_meeting(x,y+1,obj_moving_platform)//if there is a horizontal moving block under us
{
x+=instance_nearest(x,y+1,obj_moving_platform).hspeed//we move at the speed of the nearest horizontal block below us.
