I wanted to make a 60 seconds timer and used DoTaskinTime for it. Something went wrong, but i don't know what. I will be happy if you help me
Code: 

local require = GLOBAL.require

local ImageButton = require "widgets/imagebutton"

require "constants" 

AddSimPostInit(function(inst)
	GLOBAL.TheInput:AddKeyHandler(
	function(key, down)
		if not down then return end
		if key == GLOBAL.KEY_R then
			if GLOBAL.TheWorld.ismastersim then
				for i = 0, 60 do 
					inst:DoTaskInTime(1.0, function(inst)
						timer = 0
						GLOBAL.c_announce(timer)
						timer = timer + 1
					end)
				end 
			else
				GLOBAL.TheNet:SendRemoteExecute("timer = 0")
				for i = 0, 60 do 
					inst:DoTaskInTime(1.0, function(inst)
						GLOBAL.TheNet:SendRemoteExecute("c_announce(timer) timer = timer + 1")
					end)
				end
			end
		end
	end) 
end)

AddSimPostInit doesn't receive an entity as an argument, it has no arguments at all.

You can run the DoTaskInTime either on ThePlayer or on TheWorld, as those are entities you can call from SimPostInit.
