try

ccbSetCopperCubeVariable("orgs", ccbGetCopperCubeVariable("orgs") + 1);

You need to cast to number first. Those variables are always stored as strings and you will get '1' + 1 which is '11' not 2.

@okeoke is right my answer was too quick, use something like:

ccbSetCopperCubeVariable("orgs", Number(ccbGetCopperCubeVariable("orgs")) + 1);

or for strict integer value use

ccbSetCopperCubeVariable("orgs", parseInt(ccbGetCopperCubeVariable("orgs")) + 1);

Background / context information:

The type (number, string) that ccbGetCopperCubeVariable() returns appears to depend on the content previously set by the user.

- If you use ccbGetCopperCubeVariable() BEFORE using ccbSetCopperCubeVariable() on a new variable, the variable appears to default to an empty string, which triggers the issue mentioned by okeoke.
hadoken's updated approach should cleanly counter this issue.

- If you initialize the variable somewhere via ccbSetCopperCubeVariable(), you can afterwards safely use hadoken's first chosen approach (without the type conversion via "Number" or "parseInt").
Example:
1) Add a behavior "Before first drawing do something" to the root node of the scene (optionally check AlsoOnReload to re-run this every time the scene is reloaded/restarted).
2) On this behavior, add an "Execute javascript" action to set your variable:
ccbSetCopperCubeVariable("orgs", 0);

For variables affected by the "Set or change a Variable" editor action:
- When you use "Set", the variable seems to be initialized as a string, even if you specify a number as a value. This always leads to the issue described by okeoke.
- However, when you use "Add" on the variable or initialize the variable via "Add", it seems to be treated as a number afterwards.

Relevant code excerpts from CopperLicht to show that ccbGetCopperCubeVariable() supports "type aware" output and maps internally stored numbers to the correct format:


CL3D.CopperCubeVariable = function()
{
	this.Name = '';		
	this.StringValue = '';
	this.ActiveValueType = 0; // 0=string, 1=int, 2=float
	this.IntValue = 0;
	this.FloatValue = 0.0;
}		

function ccbGetCopperCubeVariable(varname)
{
	var scene = CL3D.gScriptingInterface.CurrentlyActiveScene;
		
	var var1 = CL3D.CopperCubeVariable.getVariable(varname, true, scene);
			
	if (var1 == null)
		return null;
		
	if (var1.isString())
		return var1.getValueAsString();
		
	if (var1.isInt())
		return var1.getValueAsInt(); //number type
		
	if (var1.isFloat())
		return var1.getValueAsFloat(); //number type
		
	return null;
}

Worth mentioning that if you set variable using coppercube action, not through JS api call it will always be string. I would explicitly cast anyway though:)

Warning:
Be careful with parseInt() if the variable hasn't been initialized yet.
If ccbGetCopperCubeVariable("orgs") returns an empty string "",
parseInt("") results in NaN (Not a Number) (tested on the webGL build).
It is safer to use Number(), if you want to use that approach.
