Greetings. I have a suggestion for a math node to add to Scratch: Linear Interpolate, or Lerp. Having used this feature in game engines like Unity and Godot, it might very well be a handy thing to have in Scratch. Similar to the glide blocks, the Lerp math could do a similar thing, but with values and properties instead of strictly positions. The math would be something like this:

float lerp (float a, float b, float t)
{
return a + t(b − a)
}

Of course, since Scratch is not a game engine, with a regular Update callback, it could also be the 2 values along with something like how many seconds it takes to interpolate between them.

What is a Lerp???

Fixed.

It is short for linear interpolate. It basically means to move from point a to point b by this amount. So, for instance, lerp from 1 to 10 by 2.

Support, I used this functionality in my triangle filler tutorial and writing out the equation was a little annoying (I try not to narrate while writing the code). This would just make everything a little easier to do and could simplify the code a little bit.

No support, as this does not seem to be a native instruction, it is better implemented with a broader suggestion such as custom reporters.
