Sometimes, you think to yourself "that's way too many", and when you do, you simplify. Rougelike games have a tendency to have attributes associated with items. Commonly, "blessed", "normal", and "cursed". In this tutorial, we'll be using the technique discussed in @{tut021_detouring.md} to give every item one of these stats by overrideing @{item.lua.RegisterItem} the Serialize() and DeSerialize() methods to give every item a little extra data. +In the last tutorial we saw how to create lots and lots of items. Sometimes, you think to yourself "that's way too many", and when you do, you simplify. Rougelike games have a tendency to have attributes associated with items. Commonly, "blessed", "normal", and "cursed". If we implemented this by detouring the item.RegisterItem() function, we would make 3 items for every 1 item in the game. Moreover, if you had 3 addons that each did this, the number of items would quickly explode to an unmanageable number. In this tutorial, we'll look at another method of giving items effects. Instead of creating items with names, we're going to override how items save and load themselves to give them a little extra data. garrysmod/addons/artery\_rougelite/data/artery/global/item\_attributes.txt diff --git a/tutorials/tut050_entities.md b/tutorials/tut050_entities.md index e443cae..f223228 100644 --- a/tutorials/tut050_entities.md +++ b/tutorials/tut050_entities.md @@ -28,6 +28,9 @@ garrysmod/addons/artery\_rougelite/data/global/entity\_fountain.txt scripted_ents.Register(ENT, "artery_fountain") +### Alter + +Use mostly the same approach.
