Hi guys,

I made a menu, loaded in a background file for test purposes and assigned a few menu items

Start

Settings

Exit

When the program first starts a flag is set to 1 so the menu appears when the program has loaded

up.

Then it goes into a while loop, while the flag is = 1, then theirs a if block for the menu items.

this is where it gets funny.. I have assigned keys to the menu as well as mouse positions, if the mouse is in location and left button is pressed or the T key is pressed then re size the screen to full screen.

It works when you press the T key but when you click it, it re-sizes the screen but does not call the menu draw function again to re-size the menu background and text.

its wierd because it works if I don't put the menu draw in its own function but then it will not re-size the background or the menu text because it can not be called from the if bock..

I have attached the lua file.

I am not getting error on the import("Scripts/functions.lua") now but its not doing it really..

this is the contents of the functions.lua

I get errors with the self. so i deleted it then errors on the context trying to index self. (nill value)

when I deleted the self I got the same but error trying to index contect (nill value)

I have googled it etc but not got much help there, I looked at some examples on the site and they work if you are using them in the editor on a asset but I want to call it from the App.lua file to tidy up the coding..

function SplashScreen()

splash = Texture:Load("Materials/splash.tex")

if startUp >= 1 then

self.context:SetColor(0,0,0)

self.context:Clear() -- Clear the context

self.context:SetColor(1,1,1)

self.context:DrawImage(splash,0,0) --Draw the splash screen

self.context:Sync(true) -- Sync so it loads the screen

Time:Delay(10000) -- Time delay of 10 sec's while the splash is displayed

startUp = 0 -- set the startUp flag to 0 so the splash screen does not

-- display on the next pass in the loop.

end -- end the if statement

return startUp --return the startup flag value so the splash screen only runs on startup of the application

end

This is basic stuff really and a noob question.

Is it possible in lua to place functions in a seperate file and to call them from lua.app

What I am wanting to do is put the code for my main menu in a function or method in another file and have it loaded in to be called in the app.lua file.

something like

require_once ('scripts/functions.lua')

then call a function to display a menu

menu();

and in the functions file have all my functions like savegame, respawn, inventury etc.

I like to do things like this as it keeps everything nice and tidy, also easy to find things when problems arise...

Yup i am new to this. and wow I only placed 15 lights on this level it looks like some of them are duplicated.. I have noticed this on some of the walls when I drag a wall out (create A wall) that 2 have been created so I have to delete one of them..

Thought I was doing something wrong so downloaded unity and tried it on there and it only created one wall so I dont know..

Anyhow, its a good job I backed the scene up before adding lights.

I have added the lights again but made sure no duplicates where there, changed the doors from glass to concrete and gave the doors room to move without collision and it run smooth as a babies bottom..

I was wanting to make some higher resolution textures for the walls etc because they look very basic and plain at the moment but I am afraid that this would introduce lag as well.....

Thank you for your help guy's its a learning curve since I last programmed over 15 years ago and then I was doing applications such as accounting software, so its a big step..

I have attached the backup file with the lights placed in without the duplicates.

Its a test map that I am using to see how things go with the assets I am creating..

OK got it.... Menu with mouse position and click on the word Start game or press the S key:

function App:Start()

--Set menu flag so the menu comes up when game is first loaded

self.menuFlag = 1

--Load a texture

self.texture = Texture:Load("Images/menuBG.tex")

--set the font and text size for the menu

local font = Font:Load("Fonts/Arial.ttf",24)

self.context:SetFont(font)

font:Release()

function App:Loop()

---If the escape key is pressed then display the menu

if self.window:KeyDown(Key.Escape) or self.menuFlag >= 1 then

self.menuFlag = 1

--pause the game??

Time:Pause()

--display the texture file for the background image

self.context:SetColor(0,0,0)

self.context:Clear()

self.context:SetColor(1,1,1)

--self.context:DrawImage(self.texture,0,0)

--reset the context colour to black and clear the contect

self.context:SetColor(0,0,0)

-- self.context:Clear()

--Draw some centered text on the screen

local text = "Press S -> Start"

local text1 = "Press T -> Settings"

local text2 = "Press X -> Exit"

--get the font that was set above

local font = self.context:GetFont()

--get the window height and width to find where you want the text

local x = self.window:GetWidth() /3

local y = self.window:GetHeight() /4

--get the text width, height and devide it by 2

tx = x - font:GetTextWidth(text)/2

ty = y - font:GetHeight()

self.context:SetBlendMode(Blend.Alpha)

self.context:SetColor(1,1,1)

self.context:DrawText(text,tx,ty)

self.context:DrawText(text1,tx,ty +40)

self.context:DrawText(text2,tx,ty + 80)

--reset blend mode

self.context:SetBlendMode(Blend.Solid)

self.context:Sync(true)

--while loop for the menu selection

while self.menuFlag >= 1 do

-- returns teh x y position of the mouse cursor

local mousePos = App.window:GetMousePosition()

-- Show the mouse cursor

self.window:ShowMouse()

if mousePos.x > tx and mousePos.x < (tx + ty / 2) and mousePos.y > ty and mousePos.y < y and self.window:MouseDown(Key.LButton) or self.window:KeyDown(Key.S) then

self.menuFlag = 0

self.window:HideMouse()

Time:Resume()

Time:Update()

elseif mousePos.x > tx and mousePos.x < (tx + ty +40 / 2) and mousePos.y > (ty + 40) and mousePos.y < (y + 40) and self.window:MouseDown(Key.LButton) or self.window:KeyDown(Key.T) then

--Maximize the window

self.window:Maximize()

elseif mousePos.x > tx and mousePos.x < (tx + ty +80 / 2) and mousePos.y > (ty + 80) and mousePos.y < (y + 80) and self.window:MouseDown(Key.LButton) or self.window:KeyDown(Key.X) then

return false

end

Hope this helps some of you...

Can anyone help with the lag, I have given all doors space around them and its still really slow...

I took the rest of the day off to play some game on ultra settings feeling happier now..

I have noticed that my high resolution assets look like the graphics did back in the mid 1990's lol

Thank you... I know I have physics problems I made a life and you can not get crates to go up on it even when child to the lifft...

January 12, 2015

I was working on my level last night and I noticed a slight fps drop, booted up today and I am getting lots of lag.

I have created a small level thats like only 2 small is rooms and a corridor and I am struggling to get over 30 FPS today where as yesterday was above 100 FPS , there are only 16000 polygons so it is not like there are a lot of them any idea's on whats going on?

Any ideas would be great

Tbh I am getting back into programming, it has been 15 years or more since I touched anything and LUA is new to me..

I will post more when I add buttons and mouse etc...

January 10, 2015

Can this get pinned its getting harder and harder to find stuff with the duplicate questions threads and the search facility not been that good

January 10, 2015

If it is still saying installed can you verify the integrity, it will redownload any missing files that way..

In steam right click on Leadwerks engine > properties > local files > verify integrity of application cache..

it is worth a go..

January 10, 2015

I also agree.

These would be seen as a big improvement and it would not even take long to implement them, so I don't see why they would not be included

January 10, 2015

oh I would e interested in this one..

January 10, 2015

I put it in this topic to limit the amount of duplicate ones you have to troll through before getting an answer, thats if you can find an answer..

and there's no problem with it, it works that's why I posted it here and not made another thread..

January 10, 2015

Have you tried setting the root gravety to 0 and the player mass to 0?

and then use the space (jump key to go up) and the crouch key to go down,

I have seen a modified fps script with crouch enabled on it here somewhere...

as of 3rd person, I have not tried that yet but I want to and a top down ....

Hope this helps...

This is my start up including splash screen:

When the game first loads it goes straight into a splash screen with a disclaimer of pre alpha development and a a little advert saying powered by LEADWERKS Game Engine.

The menu is just a basic menu for now until I code for the mouse to interact with the menu, you just use the keyboard to select a menu item.

It is not finished and gives me basic function of a menu etc, I have to tidy it up but it was 4am when I did this..

Splash Screen:

Under the App:start Function

--Load a spash screen texture

self.splash = Texture:Load("Images/splash.tex")

--Set a flag so it does not run the splash screen everytime it loops

StartUp = 1

Under the function App:Loop()

-- load a splash screen before starting the game

-- If the startUp flag is grater or equal to 1 then load the splash screen

-- so if it is not greater or equal to 1 then skip past it

if startUp >= 1 then

self.context:SetColor(0,0,0)

self.context:Clear() -- Clear the context

self.context:SetColor(1,1,1)

self.context:DrawImage(self.splash,0,0) --Draw the splash screen

self.context:Sync(true) -- Sync so it loads the screen

Time:Delay(10000) -- Time delay of 10 sec's while the splash is displayed

-- startUp = 0 -- set the startUp flag to 0 so the splash screen does not

-- display on the next pass in the loop.

end -- end the if statement

Next I put the basic's in for the main menu

Basic Menu:

function App:Start()

--Set menu flag so the menu comes up when game is first loaded
self.menuFlag = 1


--Load a texture
self.texture = Texture:Load("Images/menuBG.tex")

--set the font and text size for the menu
local font = Font:Load("Fonts/Arial.ttf",24)
self.context:SetFont(font)
font:Release()

function App:Loop()

if self.window:Closed() then return false end --If window has been closed, end the program


if self.window:KeyDown(Key.Escape) or self.menuFlag >= 1 then --If the escape key is pressed then display the menu
self.menuFlag = 1

Time:Pause() --pause the game

self.context:SetColor(0,0,0) --display the texture file for the background image
self.context:Clear()
self.context:SetColor(1,1,1)
self.context:DrawImage(self.texture,0,0)

self.context:SetColor(0,0,0) --reset the context colour to black and clear the contect
-- self.context:Clear()

--Draw some on the screen
local text = "Press S -> Start"
local text1 = "Press T -> Settings"
local text2 = "Press X -> Exit"

local font = self.context:GetFont() --get the font that was set above


local x = self.window:GetWidth()/4 --get the window height and width
local y = self.window:GetHeight()/3 -- and set it up for drawing the text

x = x - font:GetTextWidth(text)/2 -- get the text width, height and divide
y = y - font:GetHeight()/2 -- it by 2

self.context:SetBlendMode(Blend.Alpha)
self.context:SetColor(1,1,1)
self.context:DrawText(text,x,y)
self.context:DrawText(text1,x,y +40)
self.context:DrawText(text2,x,y + 80)
self.context:SetBlendMode(Blend.Solid) -- reset blend -- mode

self.context:Sync(true)

self.window:ShowMouse() --show mouse


while self.menuFlag >= 1 do --while loop for the menu selection

if self.window:KeyDown(Key.S) then
self.menuFlag = 0
self.window:HideMouse()

Time:Resume()
Time:Update()
end

if self.window:KeyDown(Key.T) then
self.window:Maximize() --Maximize the window

end

if self.window:KeyDown(Key.X) then

return false
end


end


end

This is what I did in LUA to display a splash screen and pause for 10 seconds.

I am trying to implement this in C++ but it is not doing it for some reason.

Under the App:start Function

--Load a spash screen texture
self.splash = Texture:Load("Materials/splash.tex")

--Set a flag so it does not run the splash screen everytime it loops
StartUp = 1

Under the function App:Loop()

--load a splash screen before starting the game
-- If the startUp flag is grater or equal to 1 then load the splash screen
-- It did not like it if it was just equal to 1 and it bugged out until I put the greater than in

if startUp >= 1 then

self.context:SetColor(0,0,0)
self.context:Clear() -- Clear the context
self.context:SetColor(1,1,1)
self.context:DrawImage(self.splash,0,0) --Draw the splash screen
self.context:Sync(true) -- Sync so it loads the screen

Time:Delay(10000) -- Time delay of 10 sec's while the splash is displayed
startUp = 0 -- set the startUp flag to 0 so the splash screen does not
-- display on the next pass in the loop.

end -- end the if statement

Thank you..

I must say I am getting my head around this now...

I thought it would take longer since I have not touched any code for over 15 years..

January 8, 2015

Think I have figured it out....

You would have to use the Window::GetHeight command (gets the outer height of the current window in pixels, and Window::GetWidth gets the width of the current window outer width in pixels, then you would have to drawImage to fit the screen, usefull if you have a settings options for windowed and full screen...

January 8, 2015

I am wondering if there is a way to re-size a image that is displayed with the drawImage function?

Basically the image for the background of my menu should re-size if the screen is windows or in full-screen.

the picture should be able to be resized to the resolution of the monitor etc etc..

it just looks more professional if someones got a very high resolution and your in full screen and your background image only covers half the background..

any help would be great..

thank you in advance..

Hi,

I am interested in doing a cockpit for a space type game.

I will create a model in 3DS max or blender, I am just wondering how to attach it to the first person camera in LUA, would it be a similar process as adding a HUD but not with the Draw command.

What I want to do is have clickable objects in the cockpit etc etc as well but that looks like it is the easy part lol...

I would use C++ but I am not comfortable enough with it yet so I would prefer to use LUA...

any help, I would be thank full for it..

January 6, 2015

a few things to help you debug;

Did you infact start a new C++ project?[/quote]

Yes and opened the solution in Vis studio

Are you editing the correct map? ( just opening a new project in the editor wont change the map for reasons unkown )

Yes I am opening the start.map.

Are you using the FPS prefab? ( in this case you need to remove the camera in the C++ code or it wont work )

Ahhhh did not know this did not see it in any documentation...

so this would be why the FPS prefab camera in LE editor when run and in the Vis studio editor are at different locations..

Have you compiled BOTH the debug and release version of the source?

I have now thank you for this.. where did you get this information from? its not in the documentation I have read it all twice..

As for the map needing to be called start.map - look for theese line in the App.cpp file;

std::string mapname = System::GetProperty("map","Maps/start.map");
Map::Load(mapname);

I realized this one as I have changed/loaded levels in lua before coming across to the standard edition but getting it all set up has been a pain TBH..

Thankyou for these notes they are helping a lot, I think some starting out in standard edition notes or documentation is needed because its not plug in and play like the LUA edition...

thank you again
