Hello, I am only asking a very small code which is:
All I am asking is what does this mean?
this mean that you is making linear interpolation, which is a smoothly blending between two values.
a and b represent the starting and ending values, respectively.
t is a value between 0 and 1 that controls the interpolation between a and b.

…So for example, t = 0.5 would represent the halfway point between a and b, t = 0.25 would represent going a quarter way from a to b, t = 0.75 being three quarters of the way from a to b, etc.
Also that code is wrong. The function should actually do
return a + (b - a) * t
I’m not sure where you got that 1 from.

If you want to know how the equation works:
a is your starting position when lerping.
(b - a) Is the point of difference between b, which is the position relative from a.
t works in percentages, ranging from very small fractions , all the way up to 1, which is a complete 100%. t will multiply (b - a) into a percentage of the way to b, which is how we get our transition effect.
For Example:
a = 10
b = 100
According to (b - a), (100 - 10) would equal 90 relative to the position a is in, but when t multiplies that number to 0.01 (1% of the way), a is now 10.9 due to that interpolation.
It is the same as something asking to find the percentage of the number, which in this case, its same as asking for 1% of 90.
So in math form, your interpolation would look like this:
10 + 1/100(90) = 10.9

Very good explanation! Thanks!
