So, I've been following a tutorial on how to build a basic beat em up game. I am currently stuck at the steps regarding attacking and movement, where I always receive this message upon testing.

Here is my entire code.

XSpeed = 0;
}if(keyboard_check(ord(A)))
{
XSpeed = -1*Speed;

YSpeed = 0;
if(OnGround == true){
if(keyboard_check(ord(W))){if(IsAttacking == false && I💩💩💩💩 = false){

if(XSpeed != 0 && YSpeed != 0){

y+=YSpeed*SpeedMod*.7;
}else if(XSpeed != 0 || YSpeed != 0){
x+=XSpeed*SpeedMod;
y+=YSpeed*SpeedMod;
}

}else if(OnGround == false ){
x+=XSpeed*SpeedMod;
}

if(XSpeed != 0){
image_xscale = sign(XSpeed*SpeedMod);
}

//Animates the Player based on their speed
if(XSpeed == 0 && YSpeed == 0 && OnGround == true){
SpeedMod = 1;
sprite_index = SPR_PlayerIdle;
}else if((XSpeed!=0 || YSpeed != 0) && sprite_index!=SPR_PlayerWalking && OnGround == true){
sprite_index = SPR_PlayerWalking;
}
}
YSpeed = -1*Speed;
}else if(keyboard_check(ord(S))){//If the player is on the ground, this sets their GroundY variable to their current y position
if(OnGround == true){
GroundY = y;
}

//Sets the Players' depth based on their GroundY. We're using GroundY instead of y so that even when they're in the air, they will display in fornt of and behind the right objects.
depth = -1*GroundY;
YSpeed = Speed;
}
}
XSpeed = Speed;


instance_destroy();
{}

Please, can someone tell me where i'm going wrong?

Did you look at the documentation for the function you used with A?
