GameMaker How to move object randomly?

[Tyron Deonarine]

Hello all, I need some help as i'm relatively new to GMS2.

I have a room 640x360, I have an object. I would like for that object to move randomly in the room. With the code I have, it's only moving left and right. Any guidance would be greatly appreciated. The code that I have currently is as below:

switch (state) {

#region Move Right

case slime.move_right:

var wall_at_right = place_meeting(x + 1, y, o_solid);

if (wall_at_right) {

state = slime.move_left;

}

//Direction of image

image_xscale = -1;

//Speed of image moving

x += 1;



break;





#endregion



#region Move Left

case slime.move_left:

var wall_at_left = place_meeting(x - 1, y, o_solid);

if (wall_at_left) {

state = slime.move_right;

}

//Direction of image

image_xscale = 1;

//Speed of image moving

x -= 1;

break;



#endregion

}

if z = 80
{
a = random_range(-3,3)
b = random_range(-30,30)
}


if z <= 80 z += 1
else z = 0
if z > 50 mp_potential_step(x + a ,y + b , 2 , true)

It might have flaws and be inefficent but this is how it works:
put this in the step event and it counts up to 80 waits for 50 frames and moves for 30 frames
when it reaches 80 it randomizes the points again then waits for 50 frames
