dxDrawing - How to make it relative ?

[papam77]

Hello, i wanna do something with the dx, but i don't know how to make it relative, it's not same as gui.

Can someone help me ?

[MIKI785]

use guiGetScreenSize and maths, that's all you need.

[papam77]

function draw() 
local x,y = guiGetScreenSize() 
x = 1920 
y = 1080 
  
dxDrawText ( "Ahoj",631.6,611.0,732.0,766.0,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,false) 
end 
addEventHandler ( "onClientResourceStart", draw ) 

So this will be for every resolution ?

[MIKI785]

That doesn't make sense..

local x,y = guiGetScreenSize() 
dxDrawText ( "Ahoj",x/2,y/2,x/2,y/2,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,false) 

This will draw the text at the centre of the screen (it will start at the centre).

Btw. you got error in your addEventHandler... check the syntax on wiki.

[papam77]

and tell me why this x/2,y/2,x/2,y/2

[MIKI785]

'Cause maths?

[papam77]

And why /2 ? Why not /3 ?

[MIKI785]

What's your grade from maths? ...

Why would you divide it by 3 if you want centre? I can't explain it, its basic maths and logic as well

[papam77]

My grade is 3

My math grade is 12 class. And i realy don't get your "/2". He asked how to make it relative not how to make it centered and the size half of the resolution....

How to make it :

place the window where you want. Like 400,300 on 1152x864 resolution. After that make the math using calculator.

X = 400/1152

Y = 300/864

Then in dxDraw you put. dxDrawImage(ScreenW*X,ScreenH*Y,.......) this will be at the same place on every resolution.

I hope you get it.

[MIKI785]

That was just an example.

If he had read the wiki he would find all you posted here in the guiGetScreenSize documentation, it's nicely explained there.

bandi94, Thank you very much

MIKI785, The code which you've gave me, it's show the image only for 1sec and then is image deleted, but why?

[MIKI785]

You probably didn't put the event handler on that function.

Post the code.

[bandi94]

IF you don't remove the "OnClientRender" then must show of not to disapear.

Make shure "local x,y = guiGetScreenSize()" is outside of the function. Or post the code then i can help you.

I use the Gui Editor for get the relative position.

Example i make the label for get the relative position type : 0.49, 0.65, 0.13, 0.03 ok so . . .

If i want use this on dxdraw i make this

  
local x,y = guiGetScreenSize() 
a = 0.49 
b = 0.65 
c = 0.13 
d = 0.03 
dxDrawText ( "text", a*x , b*y , c*x , d*y , ........... 
-- is only example 
  

[papam77]

function design () 
local x,y = guiGetScreenSize() 
dxDrawText ( "Ahoj",x/2,y/2,x/2,y/2,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,true) 
  
  
  
  
  
  
  
  
  
end 
addCommandHandler ("test", design ) 

[bandi94]

function design () 
local x,y = guiGetScreenSize() 
dxDrawText ( "Ahoj",x/2,y/2,x/2,y/2,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,true) 
end 
  
  
local on=false 
  
function toggle() 
    if not on then 
addEventHandler ( "onClientRender", root, design ) 
on=true 
    else 
removeEventHandler ( "onClientRender", root, design ) 
on=false 
     end 
end 
  
addCommandHandler ("test", toggle ) 

P.S DxFunction's need "addEventHandler ( "onClientRender", root, function)" and not CommandHandler or other event's

[papam77]

Now i don't see it.

Then try it simpel.

function design () 
local x,y = guiGetScreenSize() 
dxDrawText ( "Ahoj",x/2,y/2,x/2,y/2,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,true) 
end 
  
addEventHandler ( "onClientRender", root, design ) 

P.S it should work the first one to : first "test" command = show it , secound "test" command hide it

[MIKI785]

There's no need of getting the resolution every frame. Put the x, y = guiGetScreenSize() at the top of the script.

[papam77]

Now it works, ty

[papam77]

But here is little problem.

function design () 
local x,y = guiGetScreenSize() 
a = 0.23 
b = 0.21 
c = 0.19 
d = 0.04 
  
dxDrawText ( "TEXT",a*x,b*x,c*x,d*x,tocolor(0,255,255,255),1.0,"bankgothic","left","top",false,false,true) 
end 
  
addEventHandler ( "onClientRender", root, design )

Label output:

guiCreateLabel(0.23, 0.21, 0.19, 0.04, "", true)    

So why it isn't on the label's place?

[MIKI785]

Dont double post!

The problem is that youre using screen width (x) to calculate positions on Y axis...
