ofxanimatable's Introduction

ofxAnimatable

Set up very simple animations, with curves, repeat modes and basic scheduling.

Let's see how to make a value animate indefinitely between two values, with an EaseInEaseOut curve.

ofxAnimatableFloat	anim;

setup(){		

	//set initial position
	anim.reset( 0.0f );

	//set repeating style
	anim.setRepeatType(LOOP_BACK_AND_FORTH);

	//set animation curve
	anim.setCurve(EASE_IN_EASE_OUT);

	//start the animation, go from current val to the specified val
	anim.animateTo( 1.0f );

}

update(){
	//update with App timebase (60 fps)
	pointAnim.update( 1.0f/60.0f );
}

Includes basic tweening curves, and customizable ones found here and here; also includes Google's Swift Out curve.

ofxAnimatable ~0.9.2 Missing Header Files

These two header files cannot be found.

#include "ofxHistoryPlot.h"

#include "ofxRemoteUIServer.h"

Animations don't work if updated by zero

Updating your animatable instance with exactly zero kills the animation going forward. It gets stuck at the reset value. On the first frame ofGetLastFrametime() returns exactly zero. So if you do this:

void update() {
    myAnimatableInstance.update(ofGetLastFrameTime());
}

You end up with a dead animation. You can fix it by doing one of these:

void update() {
    if(ofGetLastFrameTime() > 0) {
        myAnimatableInstance.update(ofGetLastFrameTime());
    }
}
//or
void update() {
    if(ofGetFrameNum() > 0) {
        myAnimatableInstance.update(ofGetLastFrameTime());
    }
}

Just thought I'd publish this in case anyone else is stuck on that.

License

Could you provide a license for the project? e.g. MIT, BSD.

How do you, handle jerky animations?

I was just curious if you had any experience with making smooth animations. As you know, frame based animations are jerky due to the fact that the framerate is not constant. Do you know how to deal with this?

can't compile in VS2017 OF 0.10 up to date...

hey @armadillu , what OF version are you building to?

"start after wait" not always working

I think the issue comes from this code:

void ofxAnimatable::update(float dt){

    if (delay_ > 0.0f ){
        delay_ -= dt;
        if (delay_ < 0.0f){
            startAfterWait();
        }
    }

It is not considering the "delay_ == 0.0f" case.
I guess the second conditional statement should be "delay_ <= 0.0f"
