Hi guys,
I’m trying to get some easing working. Currently I’m using this which doesn’t give me any easing:
pos = map(k, 0, ledRange, startPos, endPos);
How might I add some easing to k using ease8InOutCubic()?
Hummm. Seems like it needs a map run through the ease function and then mapped back to position. Here’s the test I was messing with:
Or I might have completely missed a much easier solution! The easing doesn’t really show up a small travel distance. If I set NUM_LEDS to 8 I can’t see the easing. With 32 pixels I could see some easing happening, but that’s the longest test string I have setup at this moment.
Cheers Marc. In the end I’ve used something to this effect which seems to work:
//////// start variables
int startPos = 0;
int endPos = 60;
int led_range = endPos - startPos;
int tweenDuration = 100;
//////// function
if(k>tweenDuration){
k = 0;
endPos = random(0, 500);
startPos = pos;
}
int eased = easeOutQuint(k, 0, led_range, tweenDuration);
pos = map(eased, 0, tweenDuration, startPos, endPos);
k++;
//////// function
////ease function
// current time, start value, change in value, duration
float easeOutQuint(float t, float b, float c, float d) {
t /= d;
t–;
return c*(ttttt + 1) + b;
};
Hey that looks like it’s working well. Nice job.
