Circular Movement

Hello! I'm trying to make a custom npc that moves in circles. I'm using cos for x axis and sin for y axis, but I don't know why my npc draws an ellipse
instead of a circle, being the y radius higher than x's. Am I missing something?
Here's the code:
Code: Select all
if not Layer.isPaused() or not Defines.levelFreeze then
ballTimer = ballTimer + 1
v.speedX = math.cos(ballTimer * math.pi / 180) * 0.75 --Horizontal
v.speedY = math.sin(ballTimer * math.pi / 180) * 1 --Vertical

change v.speedX to 1?

I'm not too sure what you're asking; you seem to understand that you're getting an ellipse instead of a circle because you're multiplying X by 1 and Y by 0.75. So what's the question?

Got some code for you to try:
Code: Select all
if not Layer.isPaused() or not Defines.levelFreeze then ballTimer = ballTimer + 1 v.speedX = math.cos(ballTimer * math.pi / 180) * 1 --Horizontal v.speedY = math.sin(ballTimer * math.pi / 180) * 1 --Vertical

This should definitely be "and" here.

I tried all of the above but the problem is still there.
Here's a gif showing the current npc movement. The first number shown is the X speed and the other is the Y speed.
For the people who didn't understand in the main post, I want that ball to orbit in a circle around that block.
