Spring RTS Engine

There is documentation... It may not be perfect but only a few things are unclear imo (and not the stuff you are currently dealing with). If there's a particular function you are unclear about, ask away. But you should try things out yourself first ;) Unfortunately my experiments failed. Thank you.

Man, to write something in lua, you should learn Lua Scripting . If you want world coordinate then you should use Screen & Window Geometry As I understood to get world coordinates where pointed center of view doing in such way: local w, h, x, y = Spring.GetViewGeometry() Spring.Echo( w, h, x, y ) l...

Youth nowadays has it too easy with GetScreenGeometry! In ye ole days, to retrieve screen size I had to store the arguments a DrawScreenEffects was called with! local ScreenWidthInPixels local ScreenHeightInPixels function widget:DrawScreenEffects(vsx, vsy) ScreenWidthInPixels, ScreenHeightInPixels...

Learn to debug then. I advise generously sprinkling your code with Spring.Echo, to find which blocks are run and what are the values of your variables, until you find precisely on which line it is going wrong. Have Spring windowed and use /luaui reload to shorten the change code - test in Spring cy...

you are referring to variables outside their scope

This means that you have to change

Code: Select all

function fct()
	if tst then
		local a,b = ...
	end
	Spring.Echo(a,b)
end

into :

Code: Select all

function fct()
	local a,b
	if tst then
		a,b = ...
	end
	Spring.Echo(a,b)
end

I understand. I changed it but nothing happened.

I do not know. this is the code of the original widget.

ok start by fixing this you are referring to variables outside their scope mapX, mapY and mapZ are referred out of scope next, are you *sure* you want to get the center of the screen for this, and not the mouse position? in case you want to use the mouse position, you can just use the x and y coord...

you are referring to variables outside their scope also that can't be the entirety of the code, right? yes. full code is it is part from gui_idle_builders_new.lua [code] function widget:MouseRelease(x, y, button) if not activePress then return -1 end activePress = false local iconNum = MouseOverIco...

You need to put some effort in this yourself if you want help. Post the exact error, or show what isn't working. sorry local x, y = Spring.GetViewGeometry() local result, coords = Spring.TraceScreenRay(x, y, true) if result == "ground" then local mapX, mapY, mapZ = unpack(coords) end echo(x) echo(y...

local x, y = Spring.GetCameraPosition() GetCameraPosition returns 3d coordinates of camera in world space, so is unfit as source of parameters for TraceScreenRay. What you want instead should look like: local x, y = Spring.GetViewGeometry() local result, coords = Spring.TraceScreenRay(x, y, true) i...

not the center of the map. center of the screen. as the coordinates of the mouse cursor on the map.

I assume you mean map size (screen size is resolution Spring's using): http://springrts.com/wiki/Lua_ConstGame#Map. X and Z coordinates define the map size (Y is height), so yes, it's important to specify both X and Z when giving map-specific orders. Thank you. I understand about the coordinates. m...

According to the Lua wiki: bool canReclaim Default: builder && reclaimSpeed > 0 Can the unit be issued reclaim commands? For builders only. float reclaimSpeed Default: workerTime How fast the builder can reclaim other units and features. Since all labs have workertime>0 and canReclaim is not specif...

I think this is the answer about the Factory and destination point.

I added a condition unitDefID.isFactory == false. it works.

how can I get the coordinates of the center of the screen on the map?

which means z coordinate on the map? Does it need consider when ordering others to move units.

It is LIVE))))))

now you can drag waypoint with out selection unit before.

Yes, thanks, I can see your problem now. This doesn't happen for most people and there is something specific about your configuration that's causing it. Could you rerun that demo (drag the file over spring.exe and it will play as though you are a spectator), and then after that upload the file info...

local selUnitsTbl = sprGetSelectedUnits()
to
local selUnitsTbl = GetTeamUnits(Spring.GetMyTeamID)

do i can drag waypoint with out selecting units?

Help plz )))))

all right?
