Odd gaian Cannon item struct

[alterecco]

The gaian demolition cannon seems to behave oddly when it is placed on a ship. If you do a (objGetItems gPlayerShip "*") it will return a list where the gaian is represented as "(134480194 -16777215 8 0 0" (without the ending parenthesis)

To demonstrate:

Code: Select all

(setq adder (lambda Nil
    (objAddItem gPlayerShip (itmCreate 0x08040142 1))
))

(setq printer (lambda Nil
    (enum (objGetItems gPlayerShip "*") itm (block Nil
        (dbgOutput "Item Struct: " itm)
        (dbgOutput "Item Name: " (itmGetName itm 1))
    ))
))

Run (adder) and the (printer) and you will get a list, ending with the gaian and that strange item struct.

It's a bit of a problem, since it causes code to crash with: "Mismatched open parenthesis."

There are other things that cause the same crash in mods, but the Gaian Demolition Cannon is the only one identified so far in vanilla Transcendance.

I threw together a little script and found some more.

this is what I used:

Code: Select all

(setq checking (lambda Nil
    (block Nil
        (itmEnumTypes "*" theItem
            (block Nil
                (dbgLog (itmGetName theItem 1))
                (dbgLog "Item Structure: "theItem)
                (dbgLog "------------------")
                )
            )
    )
))

These are the other items.

(I wouldn't reccomend others using dbgLog to output this much. I thought the game had crashed but, in fact, dbgLog eats alot of system resources.)

That seems to be all of them. Hope this helps.

So exactly what causes this error?

That is exactly what is unknown

Definitely a bug.

Internally, items are represented in a binary structure. When converting that to a script representation, I encode the binary structure in a string. Unfortunately, the print routines try to output the string as a binary representation and get confused.

In the next version I've fixed it so that the print routines convert the binary representation to escape-code sequences.

Thanks for the report!
