Hey! I recently discovered that lua lacks a pre-wrote function for Linear interpolation. So I decided to write my own!

```
function lerp(pos1, pos2, perc)
return (1-perc)*pos1 + perc*pos2 -- Linear Interpolation
end
```

This could be used in so many ways! From animations, to just trying to get that sweet spot on the screen. This is sure to come in handy!

EX:

```
-- Linear Interpolation
-- Use this function to perform your initial setup
function setup()
print("Hello World!")
t=1
end
function lerp(pos1, pos2, perc)
return (1-perc)*pos1 + perc*pos2 -- Linear Interpolation
end
-- This function gets called once every frame
function draw()
-- This sets a dark background color
fontSize(50)
strokeWidth(5)
background(255, 0, 221, 255)
if t > 1 then t=0 end
t = t + 0.01
-- This sets the line thickness
text("Purple rain", lerp(0, WIDTH, t), lerp(0, HEIGHT, t))
fill(255, 255, 255, 255)
-- Do your drawing here
end
```
