Hi everyone,
I've been working with tweening for text lately. I thought I'd share the code I've written; hopefully it will prove useful for others:

The header file is TextTween.h :

/*enum of Tween Methods*/
enum class TweenMethod{LINEAR,SMOOTH1,SMOOTH2,EASE_IN1,EASE_IN2,EASE_OUT1,EASE_OUT2,BOUNCE,OVERSHOOT,NONE};//for tweens
/*Text Tween Properties struct*/
struct TextTweenProperties {
	float				durationData;
	unsigned			alphaBegin;
	unsigned			alphaEnd;
	TweenMethod		alphaMethod;
	float				angleBegin;
	float				angleEnd;
	TweenMethod		angleMethod;
	unsigned			redBegin;
	unsigned			redEnd;
	TweenMethod		redMethod;
	unsigned			greenBegin;
	unsigned			greenEnd;
	TweenMethod		greenMethod;
	unsigned			blueBegin;
	unsigned			blueEnd;
	TweenMethod		blueMethod;
	float				fontSizeBegin;
	float				fontSizeEnd;
	TweenMethod		fontSizeMethod;
	float				characterSpacingBegin;
	float				characterSpacingEnd;
	TweenMethod		characterSpacingMethod;
	float				lineSpacingBegin;
	float				lineSpacingEnd;
	TweenMethod		lineSpacingMethod;
	float				xBegin;
	float				xEnd;
	TweenMethod		xMethod;
	float				yBegin;
	float				yEnd;
	TweenMethod		yMethod;
	TextTweenProperties():alphaMethod(TweenMethod::NONE),angleMethod(TweenMethod::NONE), redMethod(TweenMethod::NONE),greenMethod(TweenMethod::NONE),blueMethod(TweenMethod::NONE),fontSizeMethod(TweenMethod::NONE),characterSpacingMethod(TweenMethod::NONE),lineSpacingMethod(TweenMethod::NONE),xMethod(TweenMethod::NONE),yMethod(TweenMethod::NONE){}
};

/*TextTweenClass*/
class TextTweenClass {
private:
	unsigned			textTweenId;
	TextTweenProperties	tweenPropertiesData;
public:
	TextTweenClass(float duration=1);//apparently you NEED a default constructor to allow use in maps
	~TextTweenClass();
	TextTweenClass(const TextTweenClass& t);//copy constructor
	TextTweenClass&		operator=(const TextTweenClass& t);//copy assignment
	unsigned 			getId() const {return textTweenId;}
	TextTweenClass&		setAlpha(unsigned begin,unsigned end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setAngle(float begin,float end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setRed(unsigned begin,unsigned end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setGreen(unsigned begin,unsigned end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setBlue(unsigned begin,unsigned end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setFontSize(float begin,float end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setCharacterSpacing(float begin,float end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setLineSpacing(float begin,float end, TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setX(float begin,float end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		setY(float begin,float end,TweenMethod m=TweenMethod::LINEAR);
	TextTweenClass&		play(unsigned textId,float delay);
	bool				isPlaying(unsigned textId);
	TextTweenClass&		pause(unsigned textId);
	TextTweenClass&		resume(unsigned textId);
	TextTweenClass&		stop(unsigned textId);
};

I spent quite a few hours on this. But with it you'll be able to do the following in the template.cpp file:

+ Code Snippet

#include "TextTween.h"

int app::Loop ()
{
    static bool loaded=false;
    if (!loaded){
        int txtID = agk::CreateText("hello!");
        TextTweenClass TurnOnce(1);
        TurnOnce.setAngle(0,360).setFontSize(10,30).setY(0,200).play(txtID,4);
        loaded=true;
    }

    agk::UpdateAllTweens(agk::GetFrameTime());
    agk::Sync();
    return 0;
}

And you will have the message hello! do a 360 turn, have it's font increase from 10 to 30, and move 200 in the Y direction, taking one second for it. You can reduce the time it takes to do the turn, how many degrees, how long of a delay (I set 4 for this example), the font sizes, the amount moved in the Y direction...
This is how useful writing a class can be. You can reduce the lines of code from 5 to 2. And I am not using the other (setX, setAlpha, etc.) commands. All of them can be written on the same line. Reducing up to 12 lines into 2 lines!
Enjoy and let me know if you have trouble using it.
Cheers,
