The Universal World Owner's Manual

Here is a simple script for a 'Gather Building' - i.e. One where the user accesses a 'building' (doesnt have to be an actual building model of course, it could be a rock or a tree or a NPC..) and it gives the user a particular item (up to a defined limit).

To use it on your own world, set a building in the Buildings Editor to be a 'scripted-nowindow' type, then modify the 'AccessBuilding' Event with the building number and the item you want to award.

$kMaxAmountOfItemToGather = 3

//--------------------------------------------------
//------ Access script for Building Type 5 = Berries
//--------------------------------------------------
Event( "AccessBuilding", "5" )
{
	$ret = StandardGatherDisplay( "Berries" );
}

//--------------------------------------------------
//  StandardGatherDisplay
//--------------------------------------------------
Function	StandardGatherDisplay( $itemName )
{
	$isInInv = sysPlayerInventory( $itemName )

	if ( $isInInv < kMaxAmountOfItemToGather )
	{
		$amountToAdd = kMaxAmountOfItemToGather - $isInInv
		*changeinventory %PLAYER% $amountToAdd $itemName
		*updateinventory %PLAYER%
		*notify %PLAYER% You collected $amountToAdd $itemName
	}
	else
	{
		*alert %PLAYER% You have all the $itemName you can carry right now
	}
}
