quakeboy / Calculating Clicks per minute
Last active December 21, 2015 04:29
Calculating clicks per minute based on mouse clicks. Needed to calculate something for my game
if (e.type == MouseEvent.MOUSE_DOWN)
{
if (last_dt == 0) //first time. no avg yet.
{
last_dt = getTimer();
}
else
{
if (new_dt == 0) //second time, first cps, first average

quakeboy / vector to direction index for 8 directional movement and sprite state settings
Created August 17, 2013 11:15
Converting angle to indexes, or vector -> angle -> indexes.. I have done this at least 4 times in my life for various games/projects before, yet have to do it each time again. So here is a gist for it
float degangle = atan2f(t_dir.x, t_dir.y)*180/M_PI;
//pushing it down, so that -22.5 becomes the new 0
degangle += 22.5f;
//now making the final range as 0 - 360
if (degangle < 0) degangle += 360;
//now this var is ranged 0 - 7, with -22.5f to 22.5f being 0 and so on...
m_DirectionIndex = (int)floorf(degangle/22.5f);
