TF2 Econ Data

☕ fund my caffeine addiction ☕

A library to get TF2 item data from game memory, intended as a successor to TF2ItemsInfo and TF2IDB. No more parsing the schema file and maintaining your own structure for plugin support.

I got bored one day and thought about rewriting a few of my internal plugins so they didn't depend on external tooling anymore.

There's a semi-guide on porting from existing libraries to this one, as well as a WIP plugin that implements the natives from those libraries.

Installation

1. Download all the non-source code files in the latest release.
2. Copy tf_econ_data.smx to addons/sourcemod/plugins/.
3. Copy tf2.econ_data.txt to addons/sourcemod/gamedata/.
4. If you're a developer, copy tf_econ_data.inc to addons/sourcemod/scripting/include/ (or the appropriate path for your compiler toolchain / project).

Features

• Retrieve certain properties of an item given its definition index, including entity class name, level range, and item slot.
• Get lists of definition indices filtered with a user-defined function.
• Translate an entity classname for the appropriate player class (making spawned multiclass weapons work correctly). Technically, this is just handled as a call to the game's function, but it saves you effort from adding / maintaining the SDKCall boilerplate yourself.
• Get a loadout slot name by index or translate slot indices (retrieved from item definitions) to names.
• Read attributes and attribute properties.
• Read quality and rarity names / values.
• Access item equip regions and their equip region overlap masks, so you can determine if two wearable items are overlapping. Also access equip region names / group indices.
• Get lists of valid particle definitions, either as a whole or only for hats / taunts / weapons. (Internally, the game doesn't do anything special for the particles labled other_particles and killstreak_eyeglows.)
• Get a list of all valid paintkit proto definition indices.
• Directly get the addresses of any supported definition type, as well as the schema / protobuf schema, in case you want to do something the library doesn't support out of the box.

Note that the abstractions are intentionally low; this plugin doesn't implement higher-level functions in SourcePawn to do things like:

• Check for equipment conflicts based on multiple definition indices.
• Resolve paintkit protodefs to their items to determine paint rarity.
• Provide hardcoded filters on cosmetic particles that are not obtainable from crates (map stamps, pipe smoke).
• Determine which items can be Australium.

Example

Dump the taunt defindices for a given class:

int g_iTauntSlot = -1;

public void OnAllPluginsLoaded() {
	// you could use a hardcoded value of 11 if you want to bet on valve not changing indices
	g_iTauntSlot = TF2Econ_TranslateLoadoutSlotNameToIndex("taunt");
	if (g_iTauntSlot == -1) {
		SetFailState("Failed to determine index for slot name '%s'", "taunt");
	}
	
	ArrayList tauntList = TF2Econ_GetItemList(FilterClassTaunts, TFClass_Scout);
	
	for (int i = 0; i < tauntList.Length; i++) {
		int defindex = tauntList.Get(i);
		PrintToServer("%d", defindex);
	}
	delete tauntList;
}

/**
 * Returns true if the given item is available for the given playerClass as a taunt.
 */
public bool FilterClassTaunts(int defindex, TFClassType playerClass) {
	return TF2Econ_GetItemSlot(defindex, playerClass) == g_iTauntSlot;
}
