loveJS is an attempt to copy the LÖVE API into javascript.
The goal is to make it easy for LÖVE users to make webgames, and to port their games.
Example
The source for this example
Code: Select all
//Create an object.
obj = {};
//Load in the image
//love.graphics.newImage(url);
obj.image = love.graphics.newImage("pyramid.png");
//Load in the image
//love.audio.newSource(url);
obj.bounce = love.audio.newSource("bounce.ogg");
//Get a new font
//love.graphics.newFont(name,size);
obj.font = love.graphics.newFont("arial",15);
//All the other properties
obj.x = 200;
obj.y = 250;
obj.r = 1;
obj.sx = 1;
obj.sy = 1;
obj.dir = 1;
obj.speed = 100;
//The main updater
love.update = function (dt) {
//Move the pyramid
obj.x = obj.x + obj.speed * obj.dir * dt;
//Make him bounce to the walls
if (obj.x > 800) {
obj.dir = -obj.dir;
obj.x = 800;
//Play a sound as he bounces
love.audio.stop(obj.bounce);
love.audio.play(obj.bounce);
}
if (obj.x<0) {
obj.dir = -obj.dir;
obj.x = 0;
love.audio.stop(obj.bounce);
love.audio.play(obj.bounce);
}
//Spin the pyramid
obj.r += 3 * dt;
//Scale the pyramid down as he gets closer to the center
obj.sx = 4*((400-obj.x)/400);
obj.sy = 4*((400-obj.x)/400);
//Speed up the pyramid's movement
if (love.keyboard.isDown("w","up")) {
obj.speed += 300 * dt;
}
//Slow down the pyramid's movement
if (love.keyboard.isDown("s","down")) {
obj.speed -= 300 * dt;
}
}
love.draw = function () {
//Set the font
love.graphics.setFont(obj.font)
//Prevent images of being blurry
love.graphics.setDefaultFilter("nearest");
//Draw the pyramid
love.graphics.draw(obj.image,obj.x,obj.y,obj.r,obj.sx,obj.sy,49,42);
//Draw the description
love.graphics.print("lovescript Demo v0.01",10,30);
love.graphics.print("A/Up to speed up",10,55);
love.graphics.print("S/Down to slow down",10,75);
love.graphics.print("Space to invert direction",10,95);
love.graphics.print("Click to position pyramid",10,115);
}
love.config = function (t) {
//Set the width/height of the canvas
t.width = 800;
t.height = 600;
}
//If a key is pressed
love.keypressed = function (key) {
//If the key pressed is space
if (key==" ") {
//Change the direction of the pyramid
obj.dir = - obj.dir;
}
}
//If a mousebutton is pressed
love.mousepressed = function (x,y,button) {
//If the left mousebutton is pressed
if (button=="l") {
//Position the pyramid
obj.y = y;
obj.x = x;
}
}
//Initialize love
love.run();Right now it has graphics, audio, keyboard and mouse. The basics to make a decent game.
I could use any help with this project. Right now I'm just implementing every function that looks possible to do in my eyes.
Currently on top of my TODO list:
- Add more not-all-too-complicated modules
Make quads work as how they are supposed to work.
Have love.graphics.draw support color change by setColor.
. Is it okay if I copy some of your methods? It would be a big help!
