Python

Setting up

You can choose to use the Python programming language for any of your projects. Open your project settings tab, click "Show advanced options" and select Python as Programming Language.

Your Python microStudio project can be exported to any target (HTML5, Windows, Mac, Linux, Android...). You can also use any of the rendering APIs for 2D or 3D, as well as any of the proposed optional libs.

Tips

Checking user inputs

User inputs can be scanned in microStudio by checking fields in keyboard, touch, mouse or gamepad interfaces. For example, to check if the key A is pressed, you can check keyboard.A. This field can actually have 3 different statuses:

• if you haven't pressed A yet in the current session, keyboard.A is undefined
• keyboard.A is equal to 1 (true in microScript) if you are currently pressing it
• keyboard.A is equal to 0 (false in microScript) if have pressed it before and are not currently pressing it

To check for such fields in Python without errors, you need to check whether the field is actually defined before you can check its value:

  if hasattr(keyboard,"A"):
    if keyboard.A:
      doSomething()

Here is a helper function that you may find useful:

def checkInput(obj,val):
  if hasattr(obj,val):
    return obj[val] != 0
  return 0

Instanciating classes

Especially when using alternative graphics libs or optional libs, you may have to instantiate JavaScript objects as if you were using the new operator in JavaScript. To do this, simply call .new on the class you want to instantiate:

  light = BABYLON.HemisphericLight.new("light", BABYLON.Vector3.new(0, 1, 0), scene)

Simple Example

def init():
  global x,y
  x = 0
  y = 0

def checkInput(obj,val):
  if hasattr(obj,val):
    return obj[val] != 0
  return 0

def update():
  global x,y
  if checkInput(keyboard,"LEFT"):
    x = x-1
  if checkInput(keyboard,"RIGHT"):
    x = x+1
  if checkInput(keyboard,"UP"):
    y = y+1
  if checkInput(keyboard,"DOWN"):
    y = y-1
  pass

def draw():
  global x,y
  screen.clear()
  screen.drawSprite("icon",x,y,30)
  pass
