Conditional Prerequisites

Is it possible for the prereq of a building to be one of two things. As in, if to build a supply depot I could have a power plant or a barracks. Thanks.

Yep

Code:

Prerequisites
Object = Building1 Building2 Building3
End

That worked good. Thank you ImmoMan

So what do you do when you want both the powerplant and the barracks?

Prerequisites
Object = AmericaPowerPlant AmericaBarracks
End
or...
Prerequisites
Object = ChinaPowerPlant ChinaBarracks
End

Kitsune: thats what the guy above just said, but it tells the game engine to choose EITHER to them

I'm wondering what you do when you want BOTH to be present as the prerequisites

Ok here's a short prerequisite tutorial:

Code:

Object = building1

Means you need building1 to build it. Pretty obvious right?

Code:

Object = building1 building2

Means you need either building1 or building2 to build it.

Code:

Object = building1
Object = building2

Means you need both building1 and building2 to build it.

Code:

Object = building1 building2
Object = building3

Means you need building3, and either building1 or building2 to build.

Code:

Object = building1 building2
Object = building3 building4

Means you need one of building1 or building2, and one of building3 or building4 to build.

If anyone here sees the similarity with booleans...
First one is just a straight

Code:

if (building1)

Second one is

Code:

if (building1 or building2)

Third one is

Code:

if (building1 and building2)

Fourth is

Code:

if ( (building1 or building2) and building3)

Fifth is

Code:

if ( (building1 or building2) and (building3 or building4) )

Ok, I hope that's everything cleared up.

you mean SCIENCE = <some science>
