Why?

I developed this library as an educational tool for those who just starting to learn Programming.

ToyGraphics library is:

• A tool allowing you to write simple graphics and game application.
• Easy enough for an absolute beginner.
• 5 years kid can immediately start programming using Turtle graphics.
• Keep the focus on programming itself.
• Uses Kotlin – a modern production programming language.
• Together with Kotlin helps to learn object-oriented and functional programming.

ToyGraphics is not:

• Tool for developing production-quality, 3D and complex games or graphics.
• Learning a particular platform API: Java AWT, JavaFx.

Use the Starter project to quickly write your first program.

Examples

// An example using coordinate system
package com.anysolo.toyGraphics.demo
import com.anysolo.toyGraphics.*

fun main() {
    val wnd = Window(800, 600)
    val gc = Graphics(wnd)

    gc.drawRect(50, 50, 300, 200)
}

// Draw a square using turtle graphics
package com.anysolo.toyGraphics.demo.turtle
import com.anysolo.toyGraphics.*

fun main() {
    val wnd = Window(800, 600)
    val turtle = Turtle(wnd)

    turtle.forward(100)
    turtle.turnRight(90.0)

    turtle.forward(100)
    turtle.turnRight(90.0)

    turtle.forward(100)
    turtle.turnRight(90.0)

    turtle.forward(100)
    turtle.turnRight(90.0)
}

// Draw a square spiral using turtle graphics
package com.anysolo.toyGraphics.demo.turtle
import com.anysolo.toyGraphics.*

fun main() {
  val wnd = Window(1024, 768)
  val turtle = Turtle(wnd)

  var step = 10

  repeat(50) {
    turtle.forward(step)
    turtle.turnRight(90.0)

    step += 10
  }
}
