Pilas.xo Project

This brings the pilas-engine game development engine to Sugar, adapting it to the needs of the Sugar platform and adding elements to your learning curve.

We seek to facilitate a teaching tool for Python and game development.

This project was developed during the 2011 Sugar Junin Day Sugar Day Junin 2011

Links to the project

• Pilas: [1]
• Activity. .XO [2]
• Code [3]
• Issues tracker [4]
• Name of branch 'pilasqt'. Command to take to the branch:

hg clone https://hugoruscitti@bitbucket.org/hugoruscitti/pilas 
cd pilas/ 
hg update pilasqt

Status

What has been done:

• Packaging the pilas-engine [5] to run on Sugar.
• Incorporation of PyQt libraries [6] into the activity
• Adding widget ninja-ide [7] , to have the interactive shell on the same screen.
• Generation of file dependencies needed for the project with PyInstaller [8]
• Creating the pilas.xo activity

To-do immediately:

• Bug: resize widgets
• Bug: set focus
• Documentation of how it is packaged with Qt activity [9] for Sugar
• define user guidelines and make mockups
• typical Pippy examples [10]
• interpreter and code editor tabs
• option to run in fullscreen or box
• list of Pilas actions and behaviors
• help tab
• persistent options
• Document examples / startup guide

Future Work

We must turn this into a roadmap ...

To-do:

• Trim list of dependencies created PyInstaller, to include only what is needed
• Incorporating autocomplete and inline help for the ninja-ide
• Use dbus [11] to communicate with the menu of others
• Incorporate Sugar persistence [persistence options or code to be developed]
• Integrate code for the pilas-engine [12] and pilas.xo

Wish list

• Refactoring to PyCairo [13]
• Incorporate into the activity the possibility of Sugar sharing
• Add interactive options on objects (such as in eToys [14] )

Getting Started

The Activity starts with the game engine initialised and a monkey (mono) preloaded. The monkey is displayed in the upper pane and the lower pane executes Python code in immediate mode

The following commands can be entered (from the Spanish documentation [15])

mono.sonreir()                  //monkey smile
mono.gritar()                   //monkey shout
mono.decir("Hello World!")  
mono.x = 100
mono.y = 100
mono.escala = 2                 //set scale
mono.rotacion = 40              //rotate 40 degrees
mono.rotacion = [360]           // the [] means animate
mono.x = [-200, 200]            //animate horizontally
mono.x = [-200, 200] * 5        //go side to side 5 times
mono.x = [-200, 200], 10        //animate over 10 seconds
help(mono)
pilas.ver(mono)                 //view source
mono.eliminar()                 //delete monkey
mono = pilas.actores.Mono()     //create a monkey instance
pilas.iniciar()                 //initialise the game engine
pilas.iniciar(gravedad=(0, 0))  //initialise and set gravity

There is much more, read the Spanish. [16]

Running Pilas from Pippy

This is not working, help please!

Run the following code in Pippy

import sys
sys.path.append('/home/olpc/Activities/Pilas.activity')
import pilas
pilas.iniciar()
