Variables
« on: April 01, 2015, 08:49:26 am »

Hi cameni!

The script is invoked from the console
Code: [Select]
/*
Spawn logic object
*/

var obj = "ptm/Logic/Logic";
var initCode = 'this.log_inf("Object logic created");';

Object.prototype.ptm = {initCode: initCode}

$con.exec("var $world = $eview.$query_interface('ot::js::world.get')");
$con.exec("var logic = $world.create_instance(obj, #(pos 10), #rot, false)");

// Here everything is fine
// logic.ptm.initCode == 'this.log_inf("Object logic created");'
print(logic.ptm.initCode);

next
Code: [Select]
/*
    package: ptm/Logic/Logic
    script: logic.js
*/

var init = false;

function init_chassis(param) {

}

function init_vehicle() {

}

function update_frame() {
if (!init) {
if (this.ptm) { // here always this.ptm == undefined
eval(this.ptm.initCode);
init = true;
this.log_inf("Logic initialized");
}
}
}

Where is my mistake?
I have two links to the same object, but the new property is available only where I have added a new property to the prototype object.
I have thought about this, but I'm not sure.

Question
How do I pass a variable from one context to another context

You can't. What do you want to achieve?

My idea was to have one object "Logic", after its establishment, give it the necessary data to solve any of the current task.

By analogy:
spawnCode ([params], code)   //this logic
createTrigger ([params], condition code, activate code)   //this trigger

It's not possible (and it would be dangerous) to access foreign contexts and variables from vehicle scripts. It will be possible to access vehicles from game script in the future, but there will be a mechanism for it, so that the script can get only the objects it's allowed to see, and perform only some tasks. Basically, a coordinated AI for some tasks.

Hi developers!

It would be great to have such

Code: [Select]
// global variables in user name space
var $Uns = this.$query_interface("ot::js::userNameSpace.get");

$Uns.setVariable( "varName", value);

var varName = $Uns.getVariable( "varName");
var varName = $Uns.getVariable( "varName", value); // Option. If the variable is not defined, it returns the specified value

$Uns.deleteVariable( "varName");
