rapid-render

🚀 Rapid.js

A highly efficient and lightweight WebGL renderer capable of rendering 10k sprites at 60fps.

demo ( source code )

Features:

• Fast rendering ( capable of rendering 10,000 sprites at 60fps )
• Multi-texture support ( Batch rendering based on the GPU's maximum texture units )
• Texture cropping
• Graphic
• Matrix stacking
• Color

Install

npm i rapid-render

Or use unpkg

<script src="https://unpkg.com/rapid-render/dist/rapid.umd.cjs"></script>

Import

import { Rapid } from "rapid-render"

Useage

let rapid = new Rapid({
    canvas: document.getElementById("game"),
    backgroundColor: Color.fromHex("FFFFFF")
})

// Creating textures
const cat = await rapid.texture.textureFromUrl("./cat.png")
const plane = await rapid.texture.textureFromUrl("./plane.png")
// or
// Texture.fromImageSource(img)
// Texture.fromUrl(url)
// set clip
cat.setClipRegion(
    10,10 // top-left corner of the clipped region.
    50,50 // size
)
//                      R   G   B   A
const color = new Color(255,255,255,255)
// or Color.fromHex
// Called before starting rendering
rapid.startRender()


rapid.save() // Save state
rapid.matrixStack.translate(0,0)
rapid.matrixStack.scale(1)
rapid.matrixStack.rotate(0)

//               texture offset color
rapid.renderSprite(cat,0,0, color) // draw Sprite
rapid.restore() // back to the previous saved state

// draw graphic
// Different vertices can have different colors
rapid.startGraphicDraw()
rapid.addGraphicVertex(0, 0, color)
rapid.addGraphicVertex(100, 0, color)
rapid.addGraphicVertex(100, 100, color)
rapid.endGraphicDraw()

// Called after rendering
rapid.endRender()

// set the size
rapid.resize(100,100)
