HPL1/Script Reference

Script Reference document

In this document you will find all the various scripting functions used in the Penumbra trilogy, it's good to have a basic understanding of how Angelscript works before attempting to do anything. Unlike HPL2, the HPL1 engine will crash if too many errors are present. In some cases instead of crashing the game just won't run the accompanying map's script file until the errors have been cleared up. It's also a good idea to locate a Howard Phillip Script (*.hps) file to see how it is used in the Penumbra games to get a better understanding of its functions if you get stuck here.
