Well that worked. I still find it weird though, even more so because when using a lighter it's only called once... Currently my method feels more like a hack but ooh well, it does the job.
What I ended up with:
Code:
function OnPlayerUsingItem(Player, BlockX, BlockY, BlockZ, BlockFace, CursorX, CursorY, CursorZ, BlockType, BlockMeta)
local itemUsed = ItemToString(Player:GetEquippedItem());
--Since this hook is always called twice when using buckets, we need the 2nd call which has BlockFace at -1 parameters
if (BlockFace == -1) or (itemUsed == "lighter") then
local CallBacks = {
OnNextBlock = function(a_BlockX, a_BlockY, a_BlockZ, a_BlockType, a_BlockMeta) --The actual check if the item is allowed or not
local sql = "SELECT towns.town_id, towns.nation_id, towns.town_permissions, towns.town_fire_enabled FROM townChunks INNER JOIN towns ON townChunks.town_id = towns.town_id WHERE chunkX = ? AND chunkZ = ? AND world = ?";
local parameters = {math.floor(a_BlockX / 16), math.floor(a_BlockZ / 16), Player:GetWorld():GetName()};
local town = ExecuteStatement(sql, parameters)[1];
if not (town) then --The item is used on a block that is not part of a town, so it's allowed
return false;
else
if (town[1] == GetPlayerTown(Player:GetUUID())) then
allowed = CheckPermission(town[3], RESIDENTITEMUSE);
else
if (town[2] == GetPlayerNation(Player:GetUUID())) then
allowed = CheckPermission(town[3], ALLYITEMUSE);
else
allowed = CheckPermission(town[3], OUTSIDERITEMUSE);
end
end
if (allowed == true) then
if (itemUsed == "lighter") then
if (town[4] == 0) then --If fire is disabled in this town, prevent the player from starting a fire
return false; --Prevent item use
else
return true; --Allow item use
end
else
return true; --Allow item use
end
else
return false; --Prevent item use
end
end
end
};
local EyePos = Player:GetEyePosition();
local LookVector = Player:GetLookVector();
LookVector:Normalize(); --Make the vector 1m long
local Start = EyePos + LookVector;
local End = EyePos + LookVector * 50;
return cLineBlockTracer.Trace(Player:GetWorld(), CallBacks, Start.x, Start.y, Start.z, End.x, End.y, End.z);
end
end
