Hello, i am new and i am making a side scrolling zombie shooting game and i would like my zombie to walk towards player, and please write it in code, i prefer it, oh and i already added gravity so that is no problem, oh and the code so when it runs into the wall how to i make it change direction. and one more thing; how do i get the zombie to stop at player and attack him

create event:

speed = 1
direction = 180
gravity = 0.6 //this is all i have so far, it makes him go left

this is collision eff:

if vspeed>0 //If the player is falling
{
    move_contact_solid(270,32); //Move the player down until it connects with the ground
}
if vspeed<0 //If the player is rising
{
    move_contact_solid(90,32); //Move the player up until it connects with the ceiling
}

vspeed=0 //Stops the player from continuing its movement

Help Sum1 Please!?

What a run-on sentence , I'm quite bad for using them myself but you remind me a rather hyperactive friend with how your topic reads.

There a numerous ways to get the Zombie to move towards the player, all rely on knowing the position of the player. We can get variables from an object using the syntax object.variable , therefore we can get the (x,y) coordinates by using obj_player.x and obj_player.y. Now I'm just going to do precisely what you ask for and not anything more advanced like pathfinding.

//We are close to the player so chase them
if (distance_to_object(obj_player) < 128)
	{
	//But not close enough to attack
	if (distance_to_object(obj_player) >16)
    	{
    	//Discover there direction we need to go in
    	if (obj_player.x > x)
        	{
        	Dir = 1 ;
        	x += 2 ;
        	}
    	else
        	{
        	Dir = -1;
        	x -= 2 ;
        	}
    	}
	else
    	{
    	//Stop and Attack in Here, by virtue of skipping the nested if statement you and moving via iterating the x variable we don't need to do anything to stop only to attack
    	
    	}
	}
else
	{
	if !place_meeting(x+2*Dir,y,obj_wall)
    	{
 		x += 2*Dir ;
    	}
	else
    	{
    	Dir *= -1 ; 
    	}
   
	
	}

Now this will move toward the players x value while you are within a range , You should probably do a place_meeting check before moving in the first two moving parts.


Edit : I see in the time I wrote this up you bumped your topic blatantly ignoring the rules. You may only bump, that is to post immediately after one of your posts, every 48 hours. Please respect the rules.

thank you, im going to try this out!

[Koolman11]

i got an error here for dir as an unknown variable:

if !place_meeting(x+2*Dir,y,o_wall)

[@Alex@]

I just told you off for bumping illegally, so what do you do? you bump illegally. You didn't declare the Dir variable , I don't think this is something that needs explaining declare it as either 1 or -1 in the create event of your object.

thank you, but what do i edit other than the names of the objs? my zombie just keeps going right...

speed = 1
gravity = 0.6

//We are close to the player so chase them
if (distance_to_object(o_player) < 128)
        {
        //But not close enough to attack
        if (distance_to_object(o_player) >16)
        {
        //Discover there direction we need to go in
        if (o_player.x > x)
                {
                Dir = 1 ;
                x += 2 ;
                }
        else
                {
                Dir = -1;
                x -= 2 ;
                }
        }
        else
        {
        //Stop and Attack in Here, by virtue of skipping the nested if statement you and moving via iterating the x variable we don't need to do anything to stop only to attack
        
        }
        }
else
        {
        Dir = 1
        if !place_meeting(x+2*Dir,y,o_wall)
        {
                x += 2*Dir ;
        }
        else
        {
        Dir *= -1 ; 
        }
   
        
        }
