OnTechTreeNodeUnlock

OxideCarbonTechTree

Called when a tech tree node is unlocked.

object OnTechTreeNodeUnlock(Workbench workbench, TechTreeData.NodeInstance local5, BasePlayer local0)

Works — the game method in this build is the one the hook was written for.

Parameters

workbench: Workbench
local5: TechTreeData.NodeInstance
local0: BasePlayer

Return value

objectReturn non-null to cancel the game action.

Example

object — you can affect the game: return a value to change or cancel the action.

private object OnTechTreeNodeUnlock(Workbench workbench, TechTreeData.NodeInstance local5, BasePlayer local0)
{
    Puts("OnTechTreeNodeUnlock");

    // change nothing — the game continues as usual
    return null;

    // to affect the game:
    // return false; // non-null cancels the game action
}

Works in both Oxide and Carbon: Carbon loads Oxide plugins as is.
