Prevents conflicts when multiple CoreScript subsystems are trying to override
|
|
the mouse cursor at the same time. This uses a stack approach similar to how
|
|
ContextActionService works. The most recent override takes precedence, and any
|
|
previously set overrides will remain on the stack beneath it until removed.
|
|
|
|
Example usage:
|
|
local MOUSE_OVERRIDE_KEY = Symbol.named("PurchasePrompt")
|
|
MouseIconOverrideService.push(MOUSE_OVERRIDE_KEY, Enum.OverrideMouseIconBehavior.ForceShow)
|
|
MouseIconOverrideService.pop(MOUSE_OVERRIDE_KEY)
|
|
]]
|
|
|
|
local UserInputService = game:GetService("UserInputService")
|
|
|
|
local FFlagUseCursorOverrideManager2 = game:DefineFastFlag("UseCursorOverrideManager2", false)
|
|
|
|
local cursorOverrideStack = {}
|
|
|
|
local function update()
|
|
local activeOverride = cursorOverrideStack[#cursorOverrideStack]
|
|
if activeOverride then
|
|
UserInputService.OverrideMouseIconBehavior = activeOverride[2]
|
|
else
|
|
UserInputService.OverrideMouseIconBehavior = Enum.OverrideMouseIconBehavior.None
|
|
end
|
|
end
|
|
|
|
return {
|
|
push = function(key, behavior)
|
|
if not FFlagUseCursorOverrideManager2 then
|
|
UserInputService.OverrideMouseIconBehavior = behavior
|
|
return
|
|
end
|
|
|
|
assert(type(key) == "userdata" or type(key) == "string")
|
|
assert(typeof(behavior) == "EnumItem")
|
|
assert(behavior.EnumType == Enum.OverrideMouseIconBehavior)
|
|
|

if entry[1] == key then

table.remove(cursorOverrideStack, idx)
