TF2 Econ Dynamic

Provides a scripting interface to inject new attributes to TF2's in-memory schema. Sort of like Hidden Dev Attributes but more flexible.

Intended to be the successor to the Custom Attribute Framework; plugins should use tf2attributes in tandem with this extension.

Note that, of course, these attributes are strictly server-side. The attributes will not be recognized on the client even if they match an existing attribute class.

Installation

Grab the latest release and copy the addons directory.

The release includes tf_econ_dynamic_compat.smx, a plugin to read configurations designed for Hidden Dev Attributes. You can also change the section headers to "auto" for attributes to be automatically allocated to unused definition indices.

Plugin Example

#include <sdkhooks>
#include <tf2attributes>
#include <tf_econ_dynamic>

public void OnPluginStart() {
	// register a new attribute class
	// to avoid conflicts with other plugins, consider namespacing it
	TF2EconDynAttribute attrib = new TF2EconDynAttribute();
	attrib.SetName("gravity decreased");
	attrib.SetClass("mycustom.mult_gravity");
	
	// this determines how attributes are combined (added, multiplied, etc.)
	attrib.SetDescriptionFormat("value_is_percentage");
	
	// this saves a copy of the attribute in the extension; it will be reapplied as needed
	attrib.Register();
	
	// the handle isn't cleared, so you can reuse the class / description under multiple names
	attrib.SetName("gravity increased");
	attrib.Register();
	
	// you could also allocate new attributes based on existing ones
	// the definition index should be reset
	attrib.Import("major move speed bonus");
	attrib.ClearDefIndex();
	attrib.SetName("move speed bonus in combat");
	attrib.Register();
	
	delete attrib;
}

// callbacks below are stubs
void OnGroundEntChangedPost(int client) {
	// determine the gravity effect
	SetEntityGravity(client, TF2Attrib_HookValueFloat(1.0, "mycustom.mult_gravity", client));
}

void OnTakeDamage(int victim) {
	// apply a temporary modified move speed modifier
	TF2Attrib_AddCustomPlayerAttribute(client, "move speed bonus in combat", 1.3, 10.0);
}
