사실 저는 Coffeescript와 sketch.js를 처음 사용하고 있습니다. 그래서 나는 html로 coffeescript를 구현할 수있는 방법을 알고 싶었습니다.coffeeScript Implementation in html
구체적으로 말해서 http://codepen.io/anon/pen/YVxzyJ은 coffeescript가 포함 된 html5 캔버스에서 sketch.js 풍선 예제를 구현하고 싶습니다. 나는 검색하려고했지만 유용한 해결책을 찾지 못했습니다.
# General Variables
sketch = Sketch.create()
particles = []
particleCount = 750
sketch.mouse.x = sketch.width/2
sketch.mouse.y = sketch.height/2
sketch.strokeStyle = 'hsla(200, 50%, 50%, .4)'
sketch.globalCompositeOperation = 'lighter'
# Particle Constructor
Particle = ->
this.x = random(sketch.width)
this.y = random(sketch.height, sketch.height * 2)
this.vx = 0
this.vy = -random(1, 10)/5
this.radius = this.baseRadius = 1
this.maxRadius = 50
this.threshold = 150
this.hue = random(180, 240)
# Particle Prototype
Particle.prototype =
update: ->
# Determine Distance From Mouse
distx = this.x - sketch.mouse.x
disty = this.y - sketch.mouse.y
dist = sqrt(distx * distx + disty * disty)
# Set Radius
if dist < this.threshold
radius = this.baseRadius + ((this.threshold - dist)/this.threshold) * this.maxRadius
this.radius = if radius > this.maxRadius then this.maxRadius else radius
else
this.radius = this.baseRadius
# Adjust Velocity
this.vx += (random(100) - 50)/1000
this.vy -= random(1, 20)/10000
# Apply Velocity
this.x += this.vx
this.y += this.vy
# Check Bounds
if this.x < - this.maxRadius || this.x > sketch.width + this.maxRadius || this.y < - this.maxRadius
this.x = random(sketch.width)
this.y = random(sketch.height + this.maxRadius, sketch.height * 2)
this.vx = 0
this.vy = -random(1, 10)/5
render: ->
sketch.beginPath()
sketch.arc(this.x, this.y, this.radius, 0, TWO_PI)
sketch.closePath()
sketch.fillStyle = 'hsla(' + this.hue + ', 60%, 40%, .35)'
sketch.fill()
sketch.stroke()
# Create Particles
z = particleCount
while z--
particles.push(new Particle())
# Sketch Clear
sketch.clear = ->
sketch.clearRect(0, 0, sketch.width, sketch.height)
# Sketch Update
sketch.update = ->
i = particles.length
particles[ i ].update() while i--
# Sketch Draw
sketch.draw = ->
i = particles.length
particles[ i ].render() while i--
이
은 sketch.js 거품 예제를 만드는 데 사용되는 커피 스크립트이며, 그것은 단지 다음과 CSS를 가지고 : 이canvas {
background: #023;
display: block;
}
당신의 대답은 나를 위해 정말 도움이 될 것입니다.
