## Getting Started

### Maven

```xml

    io.github.generaloss

    jpize-core

    24.10.3

```

### Gradle (Kotlin)

```kotlin

repositories {

    mavenCentral()

}

dependencies {

    implementation("io.github.generaloss:jpize-core:24.10.3")

}

```

## Examples

#### 1. Application

``` java

public class MyApp extends JpizeApplication {

    public static void main(String[] args) {

        // create window context

        Jpize.create(1280, 720, "Window Title")

            .icon("/icon.png")

            .build().setApp(new MyApp());

        

        // run created contexts

        Jpize.run();

    }

    

    public MyApp() { } // constructor calls before init()

    

    @Override

    public void init() { } // init() calls after Jpize.run();

    

    @Override

    public void update() { } // update loop

    

    @Override

    public void render() { } // render loop

    

    @Override

    public void resize(int width, int height) { } // calls when window resizes

    

    @Override

    public void dispose() { } // exit app

    

}

```

#### 2. 2D Graphics:

``` java

TextureBatch batch = new TextureBatch(); // canvas for textures

Texture2D texture = new Texture2D("/texture.png");

Gl.clearColorBuffer();

batch.setup();

// rotate, shear and scale for subsequent textures

batch.rotate(angle);

batch.shear(angle_x, angle_y);

batch.scale(scale);

// draw texture

batch.draw(texture, x, y, width, height);

// draw rectangle

batch.drawRect(x, y,  width, height,  color);

batch.drawRect(x, y,  width, height,  r, g, b, a);

batch.drawRect(x, y,  width, height,  r, g, b);

batch.drawRect(x, y,  width, height,  alpha);

batch.render();

```

#### 3. Fonts:

``` java

// load

Font font = FontLoader.loadDefault();

Font font = FontLoader.loadFnt(path_or_resource, linearFilter);

Font font = FontLoader.loadTrueType(path_or_resource, size, charset, linearFilter);

// options

font.options().scale = 1.5F;

font.options().rotation = 45;

font.options().italic = true;

font.options().invLineWrap = true;

// bounds

float width = font.getTextWidth(line);

float height = font.getTextHeight(text);

Vec2f bounds = font.getBounds(text);

// render

font.drawText(text, x, y);

font.drawText(batch, text, x, y);

Iterable iterable = font.iterable(text);

```

#### 4. Input:

``` java

// mouse position

Jpize.getX()  

Jpize.getY()

// scroll

Jpize.input().getScroll()  

// mouse buttons

MouseBtn.LEFT.down()     

MouseBtn.RIGHT.pressed()

MouseBtn.MIDDLE.up()

// keys

Key.ENTER.pressed()

Key.ESCAPE.down()

Key.SPACE.up()

// window

Jpize.getWidth()

Jpize.getHeight()

// FPS & Delta Time

Jpize.getFPS()

Jpize.getDT()

```
