Name:
errblock

Syntax:
(errblock List function^1 function)

Argument List:
List: A list of temporary variables. The first variable gets any error stored in it that happens.

function: The function you want to run if there is an error in the other functions.

Returns:
Whatever the last function or primitive that runs in it returns.

Category:

Description:
Allows you to run functions one right after the other. If there is an error the error is stored in the error variable and then runs the last function. If no errors the last function isn't run.

(errblock (errVar)
	(dbgOutput "Running normally")
	(divide 10 0)
	(dbgOutput "Not running normally")
	
	(dbgOutput "The error is " errVar)
	)
Displays
Running normally
The error is Division by zero (10 0) ### (divide 10 0) ###
True

Comment:
Like iserror not as useful as it could be due to many errors hard crash the game and you can't throw your own errors.

http://xelerus.de/index.php?s=functions&function=229
(sovSetDisposition &svCSCAntarctica; &svPlayer; 0)
Makes things controlled by the Antarctica sovereign not attack the player.
This is wrong.

That line of code will make the Antarctica *attack* the player. Any other value will cause the Antarctica to not attack the player. Quite simply, the site has got it backwards.

Just a small reminder:
you can find 2 new categories for the functions on Xelerus:

0.98: List all the functions that have been deprecated or changed in 0.99.

0.99: List all the new functions in 0.99, if you're interested in only them.

Okay,

Would someone be willing to compile each of the functions, together with their syntax and an example of how to use it, into a working, searchable, HTML web page? :twisted:

The obvious answer to that is yes; however, the function list in downloadable HTML format is from 2007 - three years ago. Since then we have progressed from .98d to RC8. It is also notable that many of the functions in that list did not include adequate examples of syntax usage, or explanations. This is why there is a need for an updated version which contains not only the function's name and syntax, but also an example of its usage. Some of us were not born omniscient, therefore we need help in many forms. This would be a valuable reference guide.

Please realize that there are people working on the function list in their free time, and it is a lot of work to do this. I myself have updated the functions from the start up to a certain point, and the next chance I have I will continue. The real props go to Betelgeuse who must have spent forever to compile that list. There is no omniscience involved in this process, just a lot of work and experimenting.

That said, please feel free to contribute to the function list on xelerus. I am sure one with editor rights (afaik, bimbel, Betel, digdug and me) would be happy to recieve your help.

There is also a link to a single page function list here: http://xelerus.de/functions.txt. Perhaps it will suit you better?


Edit:
Reading your post again leaves me in doubt? Have you not used the function list on xelerus? It is almost up to date with the latest RC's, and what is missing will eventually be added? It is without a doubt the most complete reference to the functions we have available (apart from the vanilla source itself). Without this list I would not have been able to do the mods I have done. I use it all the time when modding.

And some of the information there is incorrect.

For example, the entry for shpOrderEscort says that the last parameter is "a number from 0 to 35 representing the position behind the ship is it escorting". It is actually 0 to 360 and represents the degree at which the wingman will be around the ship. So a value of 90 will place the wingman directly to the left of the escorted ship and 180 will place the wingman directly to the right. The values can actually go above 360 (and probably negative) and it still places the ship correctly (720 would place the wingman directly in front of the escorted ship.

It would also probably be better to have the information as a wiki so when people find errors they can correct them.
