# Lerp vs AngleLerp

Discussion and feedback on Construct 2

### » Sun Feb 05, 2017 5:27 am

anglelerp(a, b, x) Linearly interpolate the angle a to b by x. Unlike the standard lerp, this takes in to account the cyclical nature of angles.

Can someone explain to me what angleLerp does different than Lerp would for angles?
I am not fully understanding the point.

I have an object that rotates to 180 when clicked on and back to 0 when clicked on again.
I have lerp on one and anglelerp on the other and don't see a difference.

Try instead something like 300 to 30 to see the difference.
Lerp(300,30, t) will go counter clockwise.
Anglelerp(300,30,t) will go clockwise. It basically will pick the shortest direction.

Oh that is useful.
I only needed 180, I will just use lerp.
I figure if that isn't needed then anglelerp may just add more calculations.

Thanks
