====== Part 20 - Text and Game Over ======

For our last hurrah, we'll add a score object in the top left corner of the screen and increase it for each monster shot and when the star is collected.

First the score text, graphic and object:

<code=ini>
[ScoreText]
String = 000

[ScoreGraphic]
Text  = ScoreText
Pivot = top left

[ScoreObject]
Graphic  = ScoreGraphic
Position = (-380, -280, 0)
Scale    = 2
</code>

Interesting to note the special ''Text'' definition. ''ScoreGraphic'' uses this instead of a texture from file. And the ''ScoreObject'' uses the graphic section as others before.

Now, in code, add a score variable and a scoreObject at the top of the file:

<code=cpp [highlight_lines_extra="3,4"]>
orxOBJECT *hero;
orxOBJECT *herosGun;
orxOBJECT *scoreObject;
orxS16 score = 0;
</code>

Next, create a score object and assign it to the scoreObject variable in the Init() function:

<code=cpp [highlight_lines_extra="3"]>
hero = orxObject_CreateFromConfig("HeroObject");
herosGun = (orxOBJECT*)orxObject_GetChild(hero);
scoreObject = orxObject_CreateFromConfig("ScoreObject");
</code>

Add a little function to increase the score and update the ScoreObject:

<code=cpp>
void UpdateScore(int increase){
    score += increase;

    orxCHAR formattedScore[6];
    orxString_NPrint(formattedScore, sizeof(formattedScore), "%d", score);

    orxObject_SetTextString(scoreObject, formattedScore);
}
</code>

Add 250 points whenever a monster is hit with a bullet. Add UpdateScore() function calls to:

<code=cpp [highlight_lines_extra="5,12"]>
if (orxString_Compare(senderObjectName, "BulletObject") == 0){
    CreateExplosionAtObject(pstRecipientObject, "JellyExploder");
    orxObject_SetLifeTime(pstSenderObject, 0);
    orxObject_SetLifeTime(pstRecipientObject, 0);
    UpdateScore(250);
}

if (orxString_Compare(recipientObjectName, "BulletObject") == 0){
    CreateExplosionAtObject(pstSenderObject, "JellyExploder");
    orxObject_SetLifeTime(pstSenderObject, 0);
    orxObject_SetLifeTime(pstRecipientObject, 0);
    UpdateScore(250);
}
</code>

And of course, 1000 points bonus if the star is reached. Add the following code:

<code=cpp [highlight_lines_extra="3,8"]>
if (orxString_Compare(senderObjectName, "StarObject") == 0){
    orxObject_SetLifeTime(pstSenderObject, 0);
    UpdateScore(1000);
}

if (orxString_Compare(recipientObjectName, "StarObject") == 0){
    orxObject_SetLifeTime(pstRecipientObject, 0);
    UpdateScore(1000);
}
</code>

Compile and run it. Shoot some monsters and collect the star and observe the score increasing.

That takes care of having an active score object.

A final thing for the game will be to add a game over panel when the hero dies. For this, we'll have an object that gets created using a timeline track after a two second delay. First, a game over asset:

{{ tutorials:tracks:gameover.png?nolink |}}

Save this into the ''data/texture'' folder as ''gameover.png''.

Create a simple gameover graphic and object:

<code=ini>
[GameOverGraphic]
Texture = gameover.png
Pivot   = center

[GameOverObject]
Graphic  = GameOverGraphic
Position = (0, 0, -0.1)
</code>

Create a timeline track with a single command to create the ''GameOverObject'':

<code=ini>
[PopUpGameOverTrack]
2 = Object.Create GameOverObject
</code>

Then finally, change the physics handler code, so that when the hero is destroyed, create the timeline track. After a two second delay, the ''GameOverObject'' will be created on screen:

<code=cpp [highlight_lines_extra="7,16"]>
if (orxString_Compare(recipientObjectName, "HeroObject") == 0 &&
    orxString_Compare(senderObjectName, "MonsterObject") == 0
){
    CreateExplosionAtObject(pstRecipientObject, "HeroExploder");
    orxObject_SetLifeTime(pstSenderObject, 0);
    orxObject_Enable(pstRecipientObject, orxFALSE);
    orxObject_AddTimeLineTrack(scene, "PopUpGameOverTrack");
}

if (orxString_Compare(senderObjectName, "HeroObject") == 0 &&
    orxString_Compare(recipientObjectName, "MonsterObject") == 0
){
    CreateExplosionAtObject(pstSenderObject, "HeroExploder");
    orxObject_SetLifeTime(pstRecipientObject, 0);
    orxObject_Enable(pstSenderObject, orxFALSE);
    orxObject_AddTimeLineTrack(scene, "PopUpGameOverTrack");
}
</code>

Because we never had a reference to the ''scene'' before in order to add the PopUpGameOverTrack, we'll need to make a variable reference to it at the top of the code:

<code=cpp [highlight_lines_extra="3"]>
orxOBJECT *hero;
orxOBJECT *herosGun;
orxOBJECT *scene;
orxOBJECT *scoreObject;
orxS16 score = 0;
</code>

And then set the ''scene'' variable on the  orxObject_CreateFromConfig("Scene") in the ''init()'' function:

<code=cpp [highlight_lines_extra="3"]>
scoreObject = orxObject_CreateFromConfig("ScoreObject");
orxObject_Enable(herosGun, orxFALSE);
scene = orxObject_CreateFromConfig("Scene");
</code>

Compile and run. Kill your hero and wait two seconds. The game over panel will appear:

Well friends, that's game over. If you reached the end here, great job! You've learned many of the major features of Orx.

If you need more help, go to the [[en:tutorials:main|tutorials]] section where many of these concepts are covered in greater detail.

If you need quick examples, you can visit the [[en:examples:]] section and search by subject.
