I've been modding scbw for some time, but I had only used typical tools like firegraft and datedit, until now. Even though I'm not a C++ programmer I decided to give GPTP a try and maybe figure how to do some stuff by trial and error and the famous ctrlc ctrlv method. I recreated Hardened Shields from SC2 using the tutorial on GPTP, even managed to make it as researchable upgrade. It works perfectly except for one thing. The minerals/gas cost is set to 200/200 and for some reason game displays it as 356/100. When I click to research it, it takes 200 minerals and gas . How to fix this?

You should upload the actual mod which has this issue, otherwise it is really hard to say anything other than "something is wrong somewhere".

It looks to me like a stat_txt.tbl file issue (or whatever the name of the file is).

Go to your upgrade tbl entry and double check that the first "<#>" corresponds correctly to the string type that is intended.

Unit upgrading, morphing, researching, upgrading, spell casting, etc. are of different "types" that are differentiated by Starcraft using a special "<#>" substring. (You can see the correct numbers in the legend that TBLEdit or PyTBL presents.)

Anyway, I recommend looking at the strings for some other upgrades and double-checking that the "type" of your string corresponds to the pattern of the other upgrades (that do display correctly).

Additionally: if your upgrade in upgrades.dat has a "356" in there somewhere, this string type error I have described above is /extremely/ suspect, as it is likely that SCBW is parsing the data in the upgrades.dat entry as if it were another format, thus producing the incorrect string display in-game. In fact, in my experience, TBL string errors can cause crashes and other errors as well, probably due to SCBW parsing data in an unintended way.

Thanks, that was it (<4> instead of <2>).

How did you make hardened shields?

Maybe like this:

I'll have to remember that when I have the patience to attempt gptp
