GameMaker Lock Joystick Movement To One Angle

[mar_cuz]

Hi All,

I'm trying to have my player move with the left stick of a game pad but back and forth on one angle only. So the angle can be:

 push_angle = point_direction(oGoal.x,oGoal.y, x,y);

I only want to move on that axis (push_angle) back and forth and the player cannot move from that angle, so if push left, the player will travel left, but on the specified angle. please see the attached picture demonstrating better. I only want to move back and forth along the push_angle.

my movement code:

var push_angle = point_direction(oGoalTarget.x,oGoalTarget.y,x,y);
var h_move = gamepad_axis_value(pad_num, gp_axislh);
var v_move = gamepad_axis_value(pad_num, gp_axislv);   
var pdir = point_direction(0, 0, h_move, v_move);

if (h_move != 0 && v_move !=0)  {
    speed = 2;
    direction = push_angle;
    }

please help.
thanks.

What's happening now?

Just at a glance, your code only allows you to move in one direction, so you need to reverse the direction (+180) or reverse the speed (*-1) depending on which way you press.

It doesn't even follow the angle in any direction at the moment.

I'll try reversing the angle by 180 and see what happens

I tried setting the direction to push_angle + 180 but even if I try -180 the player only moves towards the goal though now on the specific angle
