usage

var Path = require('canvas-path')


var path = new Path({
    points: [
        [[100,200], [200,123]],
        [[200,123], [300,200]]
    ],
    duration: 4000,
    easing: 'easeInOutCubic'
})

function tick(t){
    var point = path.tick(t);
    // drawPoint(point[0], point[1])  // point[0]:x, point[1]:y
    if(!path.isEnd()) requestAnimationFrames(tick)
}
requestAnimationFrames(tick)

api

path.on('start', function(point){
    // do some thing
})
.on('end', function(point){
    // do some thing
})
.on('tick', function(point, timestamp){
    // depreciate cause it's takes time.
})

demo

see the test.html in test folder.

performance

new Path() don't hold any timer in it. so, if you donot use it, it will released by the GC, that's makes it easy-to-use, and plain to handle.

chage note

• v1.0.1 LinePath is available
• v1.1.0 QuadraticPath is available
• v1.1.1 BezPath is available
• v2.0.0 change api, only use Path.of to create path. deduce the complexity to use this library.

todo

maybe modulize next time.
