Wonderland Wednesday EZScript Demo

At the February 9th Wonderland Wednesday session, Ryan Babiuch (aka Jagwire), a member of the iSocial team at the University of Missouri, demonstrated his new EZScript module. This module integrates JavaScript as a capability that can be applied to any in-world object. While this is still a work in progress and not yet available in the Module Warehouse, it is now functional enough to experiment with. Here’s a demo of how it works:

And here’s Ryan presenting at the Wonderland Wednesday session:

For those who want to experiment, Ryan has provided code below for the four examples shown in the videos, plus another script that places a message in the HUD (heads-up display) when the object is clicked. The source code for the EZScript module is currently in the wonderland-modules/unstable directory hosted on google code. The full path is: wonderland-modules/unstable/EZScript. If you want to try out EZScript on your own server, you can use Subversion to check out the code.

EZScript Examples

// Hover

for(var x = 0; x < 2; x++) {
   animateMove(cell, 0, 0.5, 0, 1);
   animateMove(cell, 0, -0.5, 0, 1);
}


// Play animation already associated with an object

AnimateCell(cell);


// Spin 

ScriptContext.enableProximityEvents();
function s() {
   spin(cell, 5, 5);
}

ScriptContext.onApproach(s, false);

// Move NPC

ScriptContext.clearCallbacks();
ScriptContext.enableMouseEvents();

var x = 0;

function walk() {
   MoveNPC(cell, x, 0, 0);
}

ScriptContext.onClick(walk, false);

// Show message in HUD

ScriptContext.enableMouseEvents();

function show() {
   ShowHUDMessage("Welcome to 
        Open Wonderland!");
}

ScriptContext.onClick(show, false)
