I was looking at the Ultimate Doom iscript for Glave Wurm, and it appears he used an opcode called "_04", which seems to control how much it swerves (the Glave Wurm spins from left to right in the mod), but a similar opcode doesn't seem to be there in the newer versions of IceCC.

Does anyone know exactly what it does, and if so, is there an equivalent for IceCC 1.3? I can't find it in the opcode list.

Setvertpos, I believe. It sets the vertical position of the sprite.

but there's a seperate opcode for setvertpos anyway, and he uses it also. why use a different one?

and it's impossible that it's setvertpos, because the weapon swerves side to side no matter what direction it is fired. If it was setvertpos, then it would appear to bounce when shooting upwards or downwards.

Here's the code:

Woah, big iscript.....

Not really, the ultralisk iscript for the mod is about three times longer.

As you can see, it is setpos: (I removed many parts of script to make it easier to read, so you can't compile it)

oh it is?

thanks.

The number in the name of an opcode from older versions goes with the opcode's actual number - the number mentioned in the opcode list I included with IceCC 1.3. Remember this for future reference.

Oh.
But it must be slightly different, because in the script one of the _04's has a value of 64000, and the weapon sprite doesn't suddenly jump up out of the screen.

It is the right opcode, it is just that the parameters were not interpreted correctly before. That is part of what IceCC 1.3 fixes - parameters in some opcodes. There are two cases of this which even make it mess up interpretation of opcodes after certain opcodes on the older versions.

You can decompile the iscript.bin from the mod to get it into 1.3 syntax
