I could give you a simple code smile

You create a path in WED name it for example: way1 and add this action to your enemy smile

Code:
define MOVEMENT_SPEED, skill1;

action enemy_follow_path
{
	var dist = 0; // entity walk speed
	var LastPos[3];
	var Dir[3];
	
	path_set(my, "way1"); // Change way1 to the name of your path set in WED
	
	while(1)
	{
		path_spline(me,my.x,dist); // spline curve for smooth walking
		dist += 12*time_step; // change this to change the walk speed
		c_move(me,vector(1*time_step,0,0),nullvector,IGNORE_YOU); // this is for collision but you donīt need
		vec_diff(Dir,my.x,LastPos);
		vec_to_angle(my.pan,Dir);
		vec_set(LastPos,my.x);*/
		ent_animate(my, "run", my.MOVEMENT_SPEED, ANM_CYCLE);
		my.MOVEMENT_SPEED += 10 * time_step;
		
		wait(1);
	}
}
