I am not good at math. So, I would really appreciate it if someone could help me to freely maneuver an object in an 'infinity symbol' trajectory.

you can use paths, they are in the game and let you edit custom pathing for an object.

Just draw one out in an infinity symbol

[Mr.Troid]

I know but I don't want to have to go to paths every time I want to do A.I.

[xshortguy]

r = sqr( lengthdir_x( maximum_distance_from_center, angle ) )
x = lengthdir_x(r, angle)
y = lengthdir_y(r, angle)

Also,

Use the parametrized form.

[Mr.Troid]

Thank you for the reference. But, when I put the object in the room it goes to upper left corner. What am I doing wrong?

//Create event
maximum_distance_from_center = 2
angle = 16


//Step event
r = sqr( lengthdir_x( maximum_distance_from_center, angle ) )
x = lengthdir_x(r, angle)
y = lengthdir_y(r, angle)
