csharp 将值从一个值范围映射到另一个值范围

Posted 2021-05-12

// OBJ C
- (CGFloat)mapValue:(CGFloat)value fromRange:(CGPoint)inputRange toRange:(CGPoint)outputRange) {
  return (value - inputRange.x) / (inputRange.y - inputRange.x) * (outputRange.y - outputRange.x) + outputRange.y;
}

// Map
function map (value, inputFrom, inputTo, outputFrom, outputTo) {
  return (value - inputFrom) / (inputTo - inputFrom) * (outputTo - outputFrom) + outputFrom;
}

// Map Prototype
Math.__proto__.map = function(value, inputMin, inputMax, outputMin, outputMax) {
  return outputMin + ((outputMax - outputMin) * ((value - inputMin) / (inputMax - inputMin)));
}

// Map
public static float Map(float value, float inputFrom, float inputTo, float outputFrom, float outputTo)
{
    return (value - inputFrom) / (inputTo - inputFrom) * (outputTo - outputFrom) + outputFrom;
}
// Map
public static Vector2 Map(Vector2 value, Vector2 inputFrom, Vector2 inputTo, Vector2 outputFrom, Vector2 outputTo)
{
    float x = Map(value.x, inputFrom.x, inputTo.x, outputFrom.x, outputTo.x);
    float y = Map(value.y, inputFrom.y, inputTo.y, outputFrom.y, outputTo.y);
    return new Vector2(x, y);
}
