Making An Acid

**clock123** · 07-25-2011, 08:04 PM

I want to create an acid, just like in the normal game at the very beginning where you go to the lab and must get the flasks to create the acid pot, the items are Chemistry Pot ,jars of Orpiment, Cuprite, Aqua Regia and lastly Calamine., And when I make the acid, I want to put each chemical on that chemistry acid doing machine at the lab it will create acid for me and then I will want to use it on a pod on the wall just like in the game.

the machine looks like

at part 2:24 you can see the chemical-acid doing machine. if anyone knows how to do all these things, then please tell.

sorry for my english. , thanks for anyone who helps.

The script in Amnesia shows how to do it. If you do want to know how to do it, that's your best chance. All it uses are items/chemicals that are placed throughout those other levels, and then have a AddUseItemCallback for each item/chemical so when used onto the laboratory kit, each sets a chemical jar active while removing the chemical from your inventory and then it checks to see if all chemicals were placed down with a local variable integer, and then once they are placed down, it has the player twist the wheels causing each chemical to be released into the chemical jar that you placed there before. Then it adds bubbling sound here and there with some cool particle systems.

Simple for the player, yet very time consuming for the scripter. Ingenious. Tongue

Hmm, I'll try copy+c and paste it into my files, where do i find the script in the files?, because I can't seem to find., I dont really know how it looks though.

Steam version:
amnesia the dark descent --> maps --> main --> ch01 --> 04_wine_cellar_lab.hps

Retail version:
amnesia the dark descent --> Redist --> maps --> main --> ch01 --> 04_wine_cellar_lab.hps

I hope this was what you're talking about, unless you're talking about inside the actual script. :/

I just realised, it's not even that complicated if you put your mind to it, because I almost know how to script it Smile

And I know how to script it. Wink

You know how to script it or got it?, If so, can you send it to me please?, I dont know how to do AddUseItemCallback or however it's called, this is what my HPS file looks like at the moment., But it seems like my game crashes everytime I want to play my custom story after I did this.

Spoiler below!

EDIT : I think I found the problem, it tells me that there's no matching signatures to "BreakMyStairs();" , What should I do?

Delete the code where it calls for BreakMyStairs.

**clock123** · 07-26-2011, 11:29 AM

Alright, that worked, but the script doesnt seem to work.. what should I do? there are any tutorial for this?

**clock123** · 07-26-2011, 12:33 PM

Alright... nevermind the acid.. I'll try making it later, perhaps I'll ask the wiki to make tutorial for this.

I got new problem, When ever I try making a shelf which moves by lever, then when I go-ingame and press to start the custom map it crashes, maybe I did something wrong?

Spoiler below!
