How does ATL Circular Motion works?

#1 Post by Kia »

I have a rotation that have either 0, 90, 180 or 270 rotation:

Code: Select all

transform pipes_rotate(r):
    rotate_pad False
    ease .2 rotate r
when it circles back to 0 it rotates backwards to 0, I'm wondering if this: https://www.renpy.org/doc/html/atl.html#circular-motion
can help me achieve a full rotation instead?
It sounds like the solution I'm looking for, but with no example, I have no Idea if it works for my case and how.

A rotation of 0 is a rotation of 0. Its position is the same as 360, but it IS a full circle behind 360, so of course it rotates back. If you want to rotate from 270 forward to 0, you need to rotate to 360.

Circular motion is just that, it moves the displayable in a circular motion around a point, but without rotating it. Think of a cabin on a ferris wheel.

Hello "Kia". Did you find a way? I use this code to (in my case fist made it bigger and fit on screen at center) rotate a pic of a whirl. Non stop, but for 4 seconds in my case:
show warp001 at center:
zoom 2.0
xalign 0.5
yalign 0.5
xanchor 0.5 yanchor 0.5
rotate 0
linear 4.0 rotate 360
repeat

The "warp001" is the pic I let rotate. Tell us what worked for you.

well, I haven't found an easy fix, but I'm a programmer, I'm sure I can make a function or something to calculate the value
