# [Core Module](https://github.com/generaloss/jpize-core)
[](https://mvnrepository.com/artifact/io.github.generaloss/jpize-core)
---
Java version: 17 +
## 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 = new Font().loadDefault();
Font font = new Font().loadFnt(path_or_resource, linearFilter);
Font font = new Font().loadTrueType(path_or_resource, size, charset, linearFilter);
// options
FontRenderOptions options = font.getRenderOptions();
options.enableCullLines(0F, Jpize.getHeight());
options.color().set(0.95, 0.95, 0.93);
options.scale().set(1.5F);
options.setRotation(45F);
options.setItalicAngle(15F);
options.setInvLineWrap(true);
// bounds
float width = font.getTextWidth(line);
float height = font.getTextHeight(text);
Vec2f bounds = font.getTextBounds(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()
// scrolling
Jpize.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.getDeltaTime()
```
