Detailed Description

These functions will help you to convert the progress value passed to the timeline callback to numeric values of different types. All functions takes these three arguments:

progress The float passed to the callback. min The minimum value it should be mapped to. max The maximum value it should be mapped to.

The formula is pretty simple: roundf((float)(max - min) * progress) + min

The are functions for signed and unsigned int + long and for float:

void TimelineCallback(byte slot, float progress)
{
  //Map to int value between 1000 and 2000:
  int intValue = TL_MapToInt(progress, 1000, 2000);

  //Map to long value between 10000 and 20000:
  long longValue = TL_MapToLong(progress, 10000, 20000);

  //Map to float value between 1.5 and 6.5:
  float floatValue = TL_MapToFloat(progress, 1.5f, 6.5f);
}

TTimeline tline(TimelineCallback, 2);
