Legacy GM Need help coding the punch mechanic!

[Liam Earles]

I really need help right now with this character I'm doing for my game, and it's getting very frustrating. I'm trying to code Idle, Walk, Jump and Punch animations together, but with one of the playable characters it's not working. Every time I crouch (Which is a cartwheel technique BTW), and punch it doesn't quite register.

Here's the create event:

view_object[0]=id

///Initialize Variables
image_speed=0.04
key_left = 0;
key_right = 0;

movespeed = 0;
grav = 0.5;
hsp = 0;
vsp = 0;
jumpspeed = 10.2;
movespeed = 7;
key_left = 0;
key_right = 0;
move = key_right - key_left;
hit=false
crouching=false
attack = 0
invincible = false
dead=false
suit=0
depth = -y;
invincibility=false
grounded=true

audio_listener_position(x, y, 0);

Here's the Step Event:

//Get the player's input
key_right = keyboard_check(vk_right)
key_left = -(keyboard_check(vk_left))
key_jump = keyboard_check(ord("X"))

//React to inputs
move = key_left + key_right;
hsp = move * movespeed;
if (vsp < 10) vsp += grav;

if (place_meeting(x,y+1,BrownBlock))
{
    vsp = key_jump * -jumpspeed
}

if !place_meeting(x, y+1, BrownBlock)
and key_jump
and ((place_meeting(x+1, y, BrownBlock)) or (place_meeting(x-1, y, BrownBlock)))
{
    vsp = -jumpspeed;
}

//Horizontal Collision
if (place_meeting(x+hsp,y,BrownBlock))
{
    while(!place_meeting(x+sign(hsp),y,BrownBlock))
    {
        x += sign(hsp);
    }
    hsp = 0;
}
x += hsp;

//Vertical Collision
if (place_meeting(x,y+vsp,BrownBlock))
{
    while(!place_meeting(x,y+sign(vsp),BrownBlock))
    {
        y += sign(vsp);
    }
    vsp = 0;
}
y += vsp;

if (invincibility > 0){
invincibility --;
}

if place_meeting(x+1,y,BottomHalfBlackBlock)
{
grav = 0
}

if !place_meeting(x+1,y,BottomHalfBlackBlock)
and keyboard_check(vk_down)
{
grav = 0.5
}

if place_meeting(x+1,y,BottomHalfGreenBlock)
{
vsp = -12.5
}

if hit=true
{
health -=0
}

if invincible=true
{
health -=0
}

if (move !=0) image_xscale = move
if place_meeting(x,y+1,BrownBlock)
{
    if (move !=0) sprite_index=sprite_AvaRight; else sprite_index=sprite_AvaStanding
}
else
{
    if (vsp < 0) sprite_index=sprite_AvaJump else sprite_index=sprite_AvaStanding
}
if grounded=false
    if place_meeting(x+1,y,BrownBlock) or place_meeting(x-1,y,BrownBlock)
    sprite_index=sprite_AvaOnWalls

Here's the Z press Event:

if crouching=false
{
sprite_index=sprite_AvaKick
image_speed=0.4
}

if sprite_index=sprite_AvaSpinTechnique
{
sprite_index=sprite_AvaSpinKick
image_speed=0.4
}
attack = 1

And here's the down press event:

sprite_index = sprite_AvaSpinTechnique
image_speed=1
crouching=true

if keyboard_check(ord("Z"))
{
sprite_index=sprite_AvaSpinKick
image_speed=0.4
}
attack = 1
