package com.osreboot.ridhvl2test;

// Statically import HvlStatics for easy access to core Ridhvl2 methods
import static com.osreboot.ridhvl2.HvlStatics.*;

import com.osreboot.ridhvl2.template.HvlTemplateI;

// [Selecting a Template]:
// - There are a number of templates to choose from!
// - HvlTemplateI automatically sets up the utilities for making games.
public class Ridhvl2Test extends HvlTemplateI{

    public static void main(String[] args){

        // [Display Configuration]:
        // - The constructor needs a HvlDisplay to describe the application window.
        // - This example creates a 144Hz, 1280x720, non-resizable window titled "Ridhvl2 Test!".
        super(144.0, new HvlDisplayWindowed(1280, 720, "Ridhvl2 Test!", false));

    // [Initialize]: 
    // - Automatically called once on program startup.
    
    @Override
    public void initialize(){
        // [Resource Loading]:
        // - Ridhvl2 defaults to searching in the "/src/main/resources" folder. 
        // - hvlLoad(String) loads any type of resource (images, sounds, etc.).
        // - Resources are stored in the order that they are loaded.
        hvlLoad("RIDHVL2.png");
    }

    //---------------------------------------------------------------------//

    // [Update]:
    // - Automatically called once every frame update.
    // "delta" is the time in seconds since the last update.
    
    @Override
    public void update(float delta){
        // [Drawing a Quad]:
        // - hvlDraw(polygon, paint) renders a polygon to the display.
        // - hvlQuad(...) creates a four-sided polygon (rectangle) described by screen coordinates.
        // - hvlTexture(int) fetches a loaded texture (using the order in which it was loaded).
        hvlDraw(hvlQuad(10, 10, 64, 64), hvlTexture(0));
