• Synchronous keyboard, mouse and gamepad input for fixed step applications.
• Multi-browser support, compatible with mobile devices and and touchscreen events.
• Currently supports input from: Mouse, Keyboard, Gamepad, Touchscreen
• Detailed API docs available on the docs folder of the project.
• Demo of the library running from the examples directory.
• TSDoc documentation available.

Sync Events

• Browser events fire at a different rate than your application logic/render code.
• This library allow to access input state for variable frame rate scenarios.
• Skip the need to process out of sync browser callbacks.

Getting Started

• Get from NPM using ` npm install syncinput –save-prod`
• Here is a small code example showing the basic functionality of the library.

import {Keyboard, Keys, Mouse, MouseButton, Touch, Gamepad, GamepadButton} from 'syncinput';

//Initialization
mouse = new Mouse();
keyboard = new Keyboard();
touch = new Touch();
gamepad = new Gamepad();

[...]

//Inside of the logic/rendering loop
mouse.update();
keyboard.update();

console.log("Position X:" mouse.position.x + " Y:" + mouse.position.y);
console.log("Delta X:" mouse.delta.x + " Y:" + mouse.delta.y);
console.log("Scroll wheel:" mouse.wheel);


if (touch.touchJustPressed(0)) 
{
	console.log("First touch point just pressed.");
}
if (touch.touchJustReleased(1)) 
{
	console.log("Second touch point just released.");
}

if(mouse.buttonPressed(MouseButton.LEFT))
{
	console.log("Mouse left is pressed");
}

if(mouse.buttonPressed(MouseButton.LEFT))
{
	console.log("Mouse left is pressed");
}

if(keyboard.keyPressed(Keys.W) || gamepad.buttonPressed(GamepadButton.UP))
{
	console.log("W is pressed or Gamepad UP is pressed");
}

if(keyboard.keyJustPressed(Keys.W))
{
	console.log("W was just pressed");
}
if(keyboard.keyJustReleased(Keys.W))
{
	console.log("W was just released");
}

• setCanvas(canvas) - Attach canvas to mouse object for position coordinated to be calculated relatively to the canvas.
• insideCanvas() - Check if mouse is inside attached canvas
• setLock(value) - Set mouse lock on/off.
