If you use online editor create text sprite 

then open your app.js and fint in it  init function 

App = function()
{
    this.init = function()
    {

then in init() add some variable:

App = function()
{
    this.init = function()
    {
      wade.app.score=0;
     ....
    }
    ....
}

Then open onUpdate funct in your text object and add:

this.getSprite(0).setText(wade.app.score);

If text sprite is not first sprite - use getSprite(1)... etc 

then find in your code fragments whitch you use for score, as example destroy something and after this action add:

wade.app.score++ //if simple increment or

//OR!!!

wade.app.score=wade.app.score+20//30,50,100 etc

Good Morning,
It did not work ... the error message appeared:
"Uncaught TypeError: Can not read property 'toString' of undefined (textSprite.js, 285: 22)." Do not have to pass the value, no?

It must work, it work

okay

open your app.js file

find init function

insrt this:

this.init = function()//find init function
	{
	    wade.app.score=0;
        
        var scoreSprite = new TextSprite('learn javascript', '64px Arial', 'blue', 'center');
        var score = new SceneObject(scoreSprite);
        wade.addSceneObject(score,true);
        wade.addEventListener(score, 'onUpdate');
        score.onUpdate = function(){
            this.getSprite(0).setText(wade.app.score)
        }
//...
...
}

Can not you just add a textsprite in the editor and that it starts with 0 and use a code so that at the time of the collision add another point?

Without abusing your goodwill ... could you give me an explanation or example of a jump using physical or not, in the simplest way please?

As example add in app.js next code:

//insert in 
App = function(){
//..here code

wade.app.onClick = function(){
  wade.app.score++;
}

//another your code

}

This simple case when click increase score.

I dont know your game logic but in any case you need some trigger for change score

if we use code from topic Doubt with collision

you see fragment^

var collidingObjects = wade.getOverlappingObjects(true);
for (var i=0; i<collidingObjects.length; i++)
{
    if (collidingObjects[i].getName() == 'some specific object name')
    {
         wade.removeSceneObject(collidingObjects[i]);//trigger 
         wade.app.score++;//insert after trigger
         break;
    }
}

The part of the collision I understood ...
But what part of the code should I put in the Textsprite object?

Sorry for being annoying but I just need this and the doubt of the jump to finish my doubts ...

From so long I persisted I got my friend ...
Thanks a lot for the help...

Can you help me with the jump too?

TextSprite must have in it upade function this:

this.getSprite(0).setText(wade.app.score)

if textsprite is not first - use this.getSprite(1)...//etc

About jump - i cant help you, because i dont make platformers and dont use phisics module

But i give you a one working method in topic Move object with keyboard
