Question

Can lerp only process 3 arguments??

2

lerp takes in exactly three arguments by design. It interpolates between the first two parameters by a weight specified with the third parameter. For example:

print(lerp(1, 2, 0.5))

Outputs “1.5” because 1.5 is exactly between 1 and 2 and we provided 1/2 as the weight.
If it helps, lerp(a, b, t) is exactly the same as a + t * (b - a) or a + b * t - a * t

How many did you want? What are you getting at or what additional arguments would you need and to what end?

Asking out of genuine interest in your question.

lerp() takes exactly three arguments, for the reason that @yesko gave, but it’s worth noting that Godot has versions of lerp() for things like Vector3, so you don’t have to do component-wise lerping in most cases.

Are you hoping to gang up multiple things in the same interpolation, or are you hoping to interpolate between more than two positions?

@hexgrid
I was thinking that perhaps they wanted a more complex lerp, like using a curve or a tween function for more complex lerp-like behaviour. If that is what the OP meant I could dig up an example of some code for them, but at the moment it is still a bit of a mystery what they intended.

PS And as for lerp variations lets not forget the fabulous lerp_angle, one of my favourites.
