func main() {
gop5js.CanvasHeight = 400
gop5js.CanvasWidth = 400
gop5js.Draw = draw
gop5js.Serve()
}
func draw() {
gop5js.Background("127")
gop5js.Ellipse(20, 20, 30, 30)
gop5js.Rect(100, 100, 20, 20)
gop5js.Text("some text here", 20, 200)
}That p5.js can access
func main() {
gop5js.Draw = draw
// set the FilesPath variable. That folder can be accessed from p5.js
gop5js.FilesPath = "files/"
// before you can use the image inside draw() the image needs to be
// loaded
gop5js.LoadImage("star", "star.png")
gop5js.Serve()
}
func draw() {
gop5js.Background("127")
x = x + 1.5
// access the loaded image
gop5js.Image("star", 50, 50, 150, 150)
}
