How do I add conditions to a building?

[Taaru 0]

I have searched up and down the forum for a simple answer to this question and haven't found it, so could someone please help me out?

All I really want to do is, for example, download a building and make reward conditions for it before it becomes available - like "game.g_population > 30000"

I know I need to add 'Conditional Building = True' in the building exemplar, and that I need to set up a LUA reward script, with pointers to LTEXT files...

I have copied the formats I've seen in other user-made LUA-LTEXT scripts (altered accordingly to fit my new building using Type/Group/Instance ID pointers, etc) 
- yet all I ever get is a greyed-out building in the menu....

AARRGGHH!  Help!

You should post the lot in question, so someone can have a look, otherwise it's almost impossible to say what went wrong.

I'm trying to add conditions to the SimGoober Hospital from the STEX (SG_6x4_GooberGenHospital_50a96908.SC4Lot).

I looked at the LUA/LTEXT script from the Census Repository (CensusRepository_dd41d65.SC4lot) - and tried to set up a similar arrangement within the SG Hospital Lot file (with new IID's for newly created LUA and LTEXT files).

For whatever reason, I can't get the conditions to show up when the mouse cursor is hovered over the SG Hospital greyed-out icon in the health menu - even though I am sure I have the LUA script pointers labelled correctly and aimed at the proper LTEXT files.

I don't know if it matters, but I use DatGen to insert/export files and SC4Tool to edit properties and LTEXT.

post the LUA file please... it's impossible to say what went wrong without it. There's little point in listing all the possible beginner's mistakes...

Okay, here it is...

-- This file defines advices for the the REWARDS

dofile("adv_rewards.lua")

building_tool_types.GOOBERHOSPITAL = hex2dec('50A96908')

------------ Reward record Goober Hospital ----

a = create_reward_cityplanning('50A96908')

function

a.condition()

     if (game.g_population > 30000) then

     return reward_state.AVAILABLE

     else

          return [[text@50A9690A]]

     end

end

--a.once = 1

a.timeout = tuning_constants.ADVICE_TIMEOUT_LONG

a.title = [[text@50A9690B

]]

a.message = [[text@50A9690C]]

a.priority = tuning_constants.ADVICE_PRIORITY_URGENT

a.mood = advice_moods.GREAT_JOB

a.persist=

1

if

(_sys.config_run == 0)

then

advices : run_triggers()

end

I don't know if this matters, but :

LUA Script TGI = 0xCA63E2A3   0x4A5E8EF6   0x50A9690D

LTEXT TGIs = 0x2026960B   0x6A386D26   0x50A9690 (A...B...C)


...Is that enough info?

[Daeley 46]

do you have a package ID line on top you forgot to copy or is it missing?

[Taaru 0]

.... it's missing

Do I add the IID of the LUA file into this line???

ex- 

--#-package:50A9690D# -- package signature

[Daeley 46]

well, it has to be a unique number starting with zero, so generally taking the IID and replacing the first digit with 0 is good practice

[Taaru 0]

OK

Thanks for your help!

Hey Daeley

It turns out there were some funky unknown properties set in the exemplars for the Goober Hospital.

in the SC4LOT there were entries in both "lot" and "main" exemplars:

"Unknown - CBE243F7 - UInt32 - 0 - 0x00000001" and "Unknown - CA9B4CA8 - UInt32 - 0 - 0x00000001"

Deleting these properties from the exemplars, combined with adding the package ID# as you suggested got the reward script working just fine.

I have no idea what those unknown properties were doing, as the hospital functions just fine with them deleted.

Just thought you might wanna know
