Multiple fonts

[Core]

What is the best way to handle multiple fonts? Currently I load new font every cycle before every drawtext... I'm very noob with lua, so could someone post short reference script.

You should load fonts on startup because they take time to load. Then you switch to those fonts during runtime which is more instant.

small example:

window = Window:Create("font example",0,0,400,300)

context = Context:Create(window)

world = World:Create()

camera = Camera:Create()

light = DirectionalLight:Create()

light:SetRotation(45,45,0)

box = Model:Box()

box:SetPosition(0,0,3)

box:SetColor(1,0,0,1)

 

lilfont = context:GetFont()

bigfont = Font:Load("Fonts/arial.ttf", 48, 1)

 

toggle = 0

 

while window:KeyDown(Key.Escape)==false do

if window:Closed() then break end

 

box:Turn(Time:GetSpeed()*0.5,Time:GetSpeed()*0.5,0)

 

if window:KeyHit(Key.Space) then toggle = 1 - toggle end

if toggle==0 then

context:SetFont(lilfont)

else

context:SetFont(bigfont)

end

 

Time:Update()

world:Update()

world:Render()

context:SetBlendMode(Blend.Alpha)

context:DrawText(string.format("FPS: %.2f",Time:UPS()),0,10)

context:DrawText("HIT SPACE",0,80)

context:Sync(true)

end

Thank you very much. context:SetFont was the key part I missed. Here is my current progress with Tittle screen:

 

Why tab is not working I don't know, sorry a bit hard to read...

 

function Script:Start()

self.Tittle = "Tittle"

self.Tittle2 = "Subtittle"

self.Menutext1 = "Press ENTER"

font1 = Font:Load("Fonts/LCD-N.ttf", 100)

font2 = Font:Load("Fonts/arial.ttf", 30)

font3 = Font:Load("Fonts/LCD-L.ttf", 30)

return true

end

 

function Script:UpdateWorld()

if window:KeyDown(Key.Enter) then

self.component:CallOutputs("Activate")

end

end

 

function Script:PostRender()

self.DisplayEnabled = true

if self.DisplayEnabled == true then

context:Clear()

context:SetFont(font1)

local font1 = context:GetFont()

local screenwidth = window:GetWidth()

local screenheight = window:GetHeight()

local x = screenwidth/2

local y = screenheight/2

context:SetBlendMode(Blend.Alpha)

context:SetColor(0,0,0)

context:DrawRect(0,0,screenwidth,screenheight,0)

context:SetColor(1,0,0)

local font1_x = (screenwidth - font1:GetTextWidth(self.Tittle))/2

local font1_y = (screenheight - font1:GetHeight())/2

context:DrawText(self.Tittle,font1_x,font1_y-200)

context:SetFont(font2)

context:SetColor(1,1,1)

context:DrawText(self.Tittle2,x+80,y-130)

local font3_x = (screenwidth - font3:GetTextWidth(self.Menutext1))/2

local font3_y = (screenheight - font3:GetHeight())/2

context:SetFont(font3)

context:DrawText(self.Menutext1,font3_x,font3_y+200)

end

context:SetBlendMode(Blend.Solid)

end

 

I'm just getting a bit frustrated for the lack of documentation... I understand that this is a one big learning experience, but feels that I spend too much time searching from the net and combining different pieces of information in to one just to put up some very basic tittle screen, for example. Every game needs an UI! There should be official tutorial for it!

 

Next step is to learn to load map after pressing enter on tittle screen, and it sounds simple enough, but I'm allready sure it is not that simple...

 

But, sorry for ranting, I love Leadwerks still I'm more angry at myself and my thick head.

Context class is doucumented in the API with examples. But there is not a GUI a gui tutorial I'm afraid.

Thanks shadmar. I'm aware of the API reference and it is very useful, but examples could be commented so noob like me would know exactly what specific line does.

 

I bought FlowGUi and it is very helpful!
