[RESOLVED] Chaos Project shop screen

[darklight]

The shop screens from CP are awesome! It's got a better interface than the default shop screens, IMO. Is there a chance this script is public, or is there something like it? I was also wondering if there was a way to show all the different stat increases above PDEF and MDEF.

I believe Juan made a very nice one, but since my game only has 1 heroine (at least for now), I'd be left with a lot of empty space.

Thanks in advance ^_^

ETA: Talk about a very quick turnaround for this request, lol

Actually it IS public. xD It's just not one of my usual scripts. I released it long time ago as part of my Blizzard Script Collection v1.0. Here you go:

Blizzard is just amazing. =)

[darklight]

Woo! Awesome! Thanks, Blizz. I just started playing CP a few days ago and I loved the shop system.  ;D

ETA: Looks like I spoke too soon. I ran into trouble when I put it in my game project. I get the following error:

Spoiler: ShowHide

I tried shuffling around the order of the scripts but it doesn't work. It crashes when I select the 'Buy' option. I can select 'Sell' but as soon as I try and sell something, it crashes with the same error. It also won't display my game font just for the items listed, but the buy/sell/leave option as well as the item descriptions are fine.

[Blizzard]

Oops! I optimized the script and missed something. I updated the script in the post before, try now.

[Nortos]

Blizzard Script Collection v1.0.

Where can I find that Blizz?

[Sally]

how is this a [bug]?

[Blizzard]

I think I fixed the bug, try the script again.

@Nortos: It's very old, I think I released my scripts all separately already. Maybe you can find it on rmrk if the post wasn't lost.

[Nortos]

I'll have a look ty

[Fantasist]

Blizzard Script Collection v1.0.

It's very old, I think I released my scripts all separately already. Maybe you can find it on rmrk if the post wasn't lost.

I know where you released your scripts, in your scripting tute

[Blizzard]

Yeah, but the script collection were all scripts in one project.

[Fantasist]

Big difference. You know, many, ahem, 'Testbeds' brag about 'collection of scripts which work together', but your scripts always work together. But you know what? The next time you update the tute package, could you include the script order also? It would be nice

[Blizzard]

Yeah, but Zeriab would first have to send me that review. xD
