Hi guys,
I think that’s my first post here, so hello to everybody.
I’m used to enjoy Processing and it has an handy function : map().
It allows to re-maps a number from one range to another.
Before trying to add it by myself in a project (which shouldn’t be quite difficult) , I wonder if Gdevelopp has already something similar maybe in expressions ?
Thanks in advance
This is the explanation of this function and also the source code :
variable2 = map(variable1, min1, max1, min2, max2);
The function establishes a proportion between two ranges of values:
min1 : min2 = max1 : max2
you can read it as: min1 is to min2 as max1 is to max2.
variable1 stores a value between the first range min1~max1.
variable2 gets a value between the second range min2~max2.
This is the equation the function solves for the programmer:
variable2 = min2+(max2-min2)*((variable1-min1)/(max1-min1))
This is the Java code behind the Processing map() function:
static public final float map(float value,
float istart,
float istop,
float ostart,
float ostop) {
return ostart + (ostop - ostart) * ((value - istart) / (istop - istart));
}
