Right, this is essential to finalising my Construction yard code, I need to make certain upgrades only available while a certain building exists, given that the MOAB upgrade for the Daisy Cutter is the closest thing to it, can I make a newly built structure grant a science while it only exists codewise (i.e, no scripts) ?

Well there's a GrantScienceUpgrade, and there's GrantUpgradeCreate. The only problem is that I'm not sure whether the science will disappear when the object is destroyed. I'm guessing not.

hmm, seems messy too to do it through Sciences...

It came to me, another way to 'disable' an upgrade is through conflicting upgrades... hmm

You see, basically I have managed to code the old C&C building placement behavior with the help of other coders, mainly ravage.

What I have left to do, is replicate some method of prepurchasing a structure before placing it, the idea is that the Cons yard has several 'Drones' to build, each of these drones are a prerequisite to certain buildings, you build one and then you can use the placement icon of that building (the Drone will be destroyed then by a weapon from that building).

The problem is, you can select any upgrade and this confuses the player about the prerequisites as you can pay for a structure yet not place it as you have not built its building prerequisites.

I suppose I am lucky to get this far, If I can implement a cancel structure button it shoudln't be too bad.

look at the buttons for capturing buildings, they are only useable after a upgrade...

CommandButton Command_AmericaRangerCaptureBuilding
Options = NEED_UPGRADE
Upgrade = Upgrade_InfantryCaptureBuilding
End

:squint:

That is interesting, however the upgrade specified is defined in an accompaning module, so eh, that would require some thinking...

I think that it would not work cause if you purchase an upgrade they need to be an Player_upgrade cause if they are a Object_upgrade the drones cannot read them ... (you will need Player_Upgrades!)
but you cannot delete Player_ugrades! so the code works only for one buildingplacement!only object_upgrades can be deleted! This i big "bug" in generals.... if this bug would be not in the game i would have an completely working code for the good ol C&C building placement...
