Pioneer dev forum

Posted: **Fri Apr 25, 2014 7:52 pm**

I found pioneer, when looking for games to play on linux. Interesting, even more after reading about the lua scripts. I like spacesims, so I a gave it a try. After some looks around, I found out that it would take a while to make enough money to buy a bigger ship to make more money. Thanks to a the lua scripts I took a shortcut to fortune and made my first billion. Mission bigger ship accomplished - back to the path of virtue. But to make your living in pioneer as a trader is harder than I thought, especially when you own a big ship. One click per item - in my case 960 per load and 1920 clicks per cargo run. I am a programmer, I have weak wrists, can't click that often :). So better typing than clicking I managed to replace the row click by buttons allowing me to by/sell 1/5/10 or 50 items at once. Filling my cargo bay with 20 clicks saves some livetime :).

1. Added 5 buy and 5 sell cells to stationColumnHeading and shipColumnHeading.
2. Moved onSell an onBuy from EquipmentTableWidgets.Pair to defaultFuncs so I can use them from CommodityMarket.lua.
3. Added config.noBuyOnRowClick and config.noSellOnRowClick params to disable onBuy and onSell triggered by shipTable.onRowClicked and stationTable.onRowClicked event (nicer counting).

4. Added local commodityButton function to return my buttons
5. Added buy1 etc. as config params to EquipmentTableWidgets.Pair call

				end
				if mode == 'buy' then
					bool = funcs.onBuy(e, funcs)
				end				
				if bool == false then
					break

			end
		end)
	return button
end

local commodityMarket = function (args)

	local stationTable, shipTable = EquipmentTableWidgets.Pair({

		noBuyOnRowClick = true,
		noSellOnRowClick = true,
		shipColumns = { "icon", "name", "amount", "sell1", "sell5", "sell10", "sell50" },
	})

	return
		ui:Grid({48,4,48},1)
			:SetColumn(0, {
				ui:VBox():PackEnd({
					ui:Label(l.AVAILABLE_FOR_PURCHASE):SetFont("HEADING_LARGE"),
					ui:Expand():SetInnerWidget(stationTable),
				})
			})
			:SetColumn(2, {
				ui:VBox():PackEnd({
					ui:Label(l.IN_CARGO_HOLD):SetFont("HEADING_LARGE"),
					ui:Expand():SetInnerWidget(shipTable),
				})
			})
end

return commodityMarket

I tested it for a while and it does not seem to affect the other scripts using EquipmentTableWidgets.lua. Would need some nicer buttons perhaps, but I was not able to add a nicer one. Maybe I should spent some more time to read code :)

That is one solution, but I think a better one would be either where you hold down the mouse button, or where you have a box/field where you could fill in how much you want to sell/buy when clicking. It would default to 1t for buying and all in cargo for selling. I guess this would take some more Lua hacking.

Also, feel free to create a github account and contribute with code and branches there, as that is the "usual" way to share code.

And welcome to the forum.

That was my first thought too, but I think it can not be handled by the lua scripts only. I am a webdeveloper living in a LAMP world and I am not sure that my understanding works for c++ too. At the moment there is only the click event enabled (LuaTable.cpp) on a table row. I think it would need two events. First is mouseDown to trigger a sell/buy loop, second is mouseUp to stop the loop. No idea how to implement it. Neither the way to implement the events nor how to write a lua function that is able to stop a loop triggered by an other function. Any suggestions for documentation? In Javascript it is called event - onmouseup, onmousedown, etc. is ther something similar in lua or c?

Thanks for help
