Detailed Description

Examples for Game Objects.

Game Objects execute in this order:
Input
Alarms
Update
Collision
Draw
Draw2D

This is the core of the engine. A GameObject is imperative for actions taken in the game world through Scenes. Every major system is inheritted within the GameObject.

A GameObject could look like:
DemoObj.h

#include "GameObject.h"
#include "AzulCore.h"
 
class DemoCollideObj;
 
class DemoObj : public GameObject {
public:
    DemoObj();
    DemoObj(const DemoObj&) = default;
    DemoObj& operator=(const DemoObj&) = default;
    ~DemoObj();
 
    void Collision(DemoCollideObj* obj);
 
private:
    GraphicObject_TextureFlat* demoGraphicsObj;
    Sprite* demoSprite;
 
    virtual void Update();
    virtual void Draw();
    virtual void Draw2D();
 
    virtual void SceneEntry();
    virtual void SceneExit();
 
    virtual void Alarm0();
    virtual void Alarm1();
    virtual void Alarm2();
 
    virtual void KeyPress(AZUL_KEY k);
    virtual void KeyRelease(AZUL_KEY k);
};
