GameMaker NEED HELP WITH ENEMY AI

[emiran]

I want the enemy ai to follow the player until the position it can hit but while the player is heading rights it works but unfortunately it doesn't function while heading left.
here is my code:

if State == enemyState.Playerseen{
if (can_see == true){
var lastPlayerPosition = inst.x
if instance_exists(inst){
var distance = point_distance(x,y,inst.x,y);
image_xscale = sign(MeleeCombatPlayer.x-x);
if image_xscale == 0 image_xscale = 1;
if (abs(distance)>30){
var Path = path_add();
mp_linear_path_object(Path,lastPlayerPosition,y,4,oWall);
path_start(Path,image_xscale *walksp,path_action_stop,false);
sprite_index = sSkeletonWalk;
State = enemyState.Playerseen;
//move_towards_point(lastPlayerPosition+(image_xscale * 70),y,walksp);
//sprite_index = sSkeletonWalk;
}
else if (abs(distance) <= 30){
path_end();
State = enemyState.Attack;
}
}
}
}
if State == enemyState.Attack{
sprite_index = sSkeletonAttack;
if (image_index > image_number - 1){
var distance = point_distance(x,y,MeleeCombatPlayer.x,MeleeCombatPlayer.y);
if (abs(distance)>30) State = enemyState.Playerseen;
if (abs(distance) <=30) State = enemyState.Attack;
}
}

I honestly cannot read that code at all. Why didn't you post it in a code block?

like = this;

Why do you use paths for so short distances when you could just use mp_potential_step?

how to implement it in this code?

Just call it with the proper coordinates, speed, precision and object to avoid, and it will change speed and direction each time it's called. It works by checking if the line from current position to goal intersects the object-to-avoid (e.g., the wall parent), and if there's an object-to-avoid in the way, it changes the movement direction left/right until it's free. It gets around simple obstacles pretty well.
