How can I go about doing this?

[Marine]

When a structure (RandomBuilding) is built, it is supposed to be replaced immediately in the same position with a new random structure (structures A, B, C, D, or E). The probability for each structure being picked is equal.

How can I go about making a trigger that allows for this? I feel like this requires variables, but I have no skill with that. So. If anyone could help me, it'd be greatly appreciated.

[TRIGGER="RANDOM BUILD'z"]
Events
A unit build blah blah
Conditions
Actions
Set B = Last build'z
Set BP = Build'z Point'z (UNIT POINT'z)
Unit - Replace B with Blah blah..[/TRIGGER]

Set BP = Build'z Point'z (UNIT POINT'z)
Unit - Replace B with Blah blah..[/TRIGGER]

I don't even.

When a structure - lets called it StructureA - is built, it is supposed to be immediately replaced by one of three structures. The choice of which structure is random. These are the structures:

StructureX
StructureY
StructureZ

How can I make a trigger that does this?

Create a unit type variable, set them at map initialization.

set variable[0] = unit type A
set variable[1] = unit type B
set variable[2] = unit type C

Unit finishes construction
Unit type of constructed structure == your unit type
Replace constructed structure with variable[randim integer between 0 and 2]
