ToT @units_advanced Column B

[MikeLynch]

Very quick question.

Column B (the "not allowed on map" mask) in the Advanced Unit Properties section of rules.txt has eight zeroes. Shouldn't it only have four? I thought four maps was the maximum.

I think it's just a programming thing.

Column B is probably stored in memory as one single byte, which is 8 bits. Only the last 4 are used.

Even so, maybe it actually is possible to get 8 maps, but I wouldn't be too sure about that.

OK, follow-up:
are those last 4 in "reverse programmer notation"? I.e., if I want Unit X to be disallowed on Map 1, would I enter the 1 bit in the eighth slot or the fifth?

 

[Mercator]

Good question... It seems to be "reverse programmer notation". So you'd put the 1 in the eighth slot.

To find out the details of the more complicated parts of the rules.txt it's a good idea to start by looking at the rules of the different ToT games.

Har har! The eighth slot is for BARBARIANS. The seventh is for the white civs, the first for purple. So it is Reverse notation.

Gotta love that "only Civ X can build" command. Like a little taste of Civ3, in ToT.
