Example

This example is directly from zp_haunted.io file 

Function OnRoundStart()
{
	FireOutput "bookbtn0" "DeActivate" "" 1.0
	FireOutput "bookbtn1" "DeActivate" "" 1.0
}

Function OnOutputSent( EntityID, EntityName, OutputName, OutputValue, OutputDelay )
{
	if EntityName is "wpn_give"
		// Give the player the shotgun
		GiveItem {OutputValue} "weapon_dbarrel"
	end

	if EntityName is "me_book"
		FireOutput "bookbtn1" "Activate" "" 1.0
	end

	if EntityName is "book_place1"
		FireOutput "bookbtn0" "Activate" "" 1.0
	end

	// The player participated in finding the anomalies
	if EntityName is "anomaly0"
		Participated {OutputValue} "HOUSEOFHORRORS"
		FireOutput "book_check" "IncreaseValue" "" 0.0
	elseif EntityName is "anomaly1"
		Participated {OutputValue} "HOUSEOFHORRORS"
		FireOutput "book_check" "IncreaseValue" "" 0.0
	elseif EntityName is "anomaly2"
		Participated {OutputValue} "HOUSEOFHORRORS"
		FireOutput "book_check" "IncreaseValue" "" 0.0
	elseif EntityName is "anomaly3"
