Overview[edit | edit source]
Accepts an input value which is remapped from it's relationship with the internal min and max input values, to a correlating relationship with the internal min and max output values.
For example, here are values used to scale an input by 10:
- Input min (m_flInMin) - 0
- Input max (m_flInMax) - 10
- Output min (m_flOut1) - 0
- Output max (m_flOut2) - 100
Sending an InValue of 5 will result in an OutValue of 50, an InValue of 10 will produce an OutValue of 100, etc. Here is the full formula used in the code, flValue is the input value:
float flRemappedValue = m_flOut1 + (((flValue - m_flInMin) * (m_flOut2 - m_flOut1)) / (m_flInMax - m_flInMin));
