Scripters cove

[JensAyton]

it still makes sense to check for "ship.docked == true

Just check if (ship.docked). Explicitly comparing to true serves no purpose except in specialized situations.

Could someone please tell me the Oolite coordinate system as it pertains to the view screen? Thanks

If I get this right you are talking about custom_views? If so then
[wiki]Shipdata.plist[/wiki] (custom_views), view_position is X,Y,Z - [0,0,0] should be the center.

Thanks for your reply. Should have been more specific as I was referring to the Forward, rear, left and right views. But I figured it out by studying the hud.plist. I have made a copy of that file to the Add Ons folder to tinker with.

[CaptSolo]

Considering this snippet from hud.plist,

Code: Select all

{	// scanner
	alpha		= 1.0;
	selector	= "drawScanner:";
	x		= 0;
	y		= 60;
	y_origin	= -1;
	height	= 72.0;
	width		= 288.0;
	rgb_color	= (1.0, 0.0, 0.0);
},

Made me ask two questions:
1) How is this procedure executed / handled?
2) How many draw procedures are there other than drawing rectangles, circles, and ellipses that a scripter could use?

Hi,

Is there a way to call a function in a world script from another one.

Like a callback passed by a string.

As an example

Word Script A
this.startUp = function()
{
this.callback="B";
}
this.B = function(option)
{
log(this.name,option);
}


And second script can retrieve the name of the call back by worldScripts("A").callback;

But I could not achieve to call the callback from second script.

[Commander McLane]

You can call any world script function from any other script by pre-fixing the world script name.

Example: this.$setUpSystem() in the Anarchies-script can be called from anywhere (including the JS-console, which is particularly useful for playtesting) with worldScripts.Anarchies.$setUpSystem().

The prefix for world scripts is worldScript (see here), which is followed by the script name (the one specified in this.name at the top of your world script). There are some special rules if your script name contains a SPACE.

[Okti]

Thanks Commander McLane,

But my problem is trying to pass the name of the function as a string property.

wordScripts("MyWordScript") gets my MyWordScript. Like this I want to call a Function in that world script by name.

[Okti]

Never mind I solved the problem.

If you say how, others will benefit from your discovery...

You are right.

The method is

Code: Select all

worldScripts["scriptname"]["functionname"](args);

I tried it at the first place but I forgot to add this. before the function name

Morning (yawn),

Anyone know if the variable ship_trade_in_factor in the save file is visible to JS and if so what's the property to access it (player.ship.something???).

Ta,

That you need to include "this." when writing it down as string is new to me. I always used:

Code: Select all

worldScripts.scriptname.functionname(args)

for calling functions with parameters in other scripts. Or

Code: Select all

worldScripts["scriptname"].functionname(args)

Both go without a "this". Writing down as string is only needed when the string contains special characters. A scriptname might contain such characters, but a function never.

ship_trade_in_factor is not exposed.

[JensAyton]

Both go without a "this". Writing down as string is only needed when the string contains special characters. A scriptname might contain such characters, but a function never.

foo.bar is purely shorthand for foo["bar"]. There is no difference in behaviour. As such, foo["Fred Bloggs"] = function () {} is perfectly valid.

[Thargoid]

But foo.fred bloggs = function() isn't due to the space (an example of the special characters).

Personally I always tend to use worldScripts["name"] rather than worldScripts.name even when name doesn't include a space or somesuch, just for consistency. But as Eric says, the functions themselves never will have such characters in them by definition.
