Adding a delay of 2 sec before enemy changes it's sprite direction?

[pixeltroid]

This very very basic code I have changes the enemy's sprite direction when the hero runs past him.

if (x<obj_hero.x) {
image_xscale = -1;
} else {
image_xscale = 1;
}

The sprite flip happens a instantly which is fine for some enemies. But I have some other enemies that I'd need to flip after a slight delay (basically give the hero 2 seconds to run away).

How should I go about implementing this?

Any help would be appreciated.

try distance delay (for a 2D platformer)

if (x < obj_hero.x - 20) image_xscale = 1;
else
if (x > obj_hero.x + 20) image_xscale = -1;

Works perfectly for my needs. Just increased the x distance to 96! Thanks!

If you do want it time based you could us an alarm.
Step event

if (alarm[0] == -1 && sign(obj_hero.x - x) != image_xscale) {
    alarm[0] = 2 * game_get_speed(gamespeed_fps);
}

Alarm 0

if (sign(obj_hero.x - x) != image_xscale) {
    image_xscale *= -1;
}

thanks. That works perfectly!

I'll implement this. But will use the distance delay for another type of enemy.
