HU/dxSetRenderTarget

This function changes the drawing destination for the dx functions. It can be used to select a previously created render target, or if called with no arguments, restore drawing directly to the screen.

Szintaxis

bool dxSetRenderTarget ( [ element renderTarget, bool clear = false ] )

If no arguments are supplied, the screen is restored as the drawing destination.

OOP Syntax Help! I don't understand this!

Method: rendertarget:setAsTarget(...)

Tetszőleges paraméter

renderTarget: The render target element whose pixels we want to draw on.
clear: If set to true, the render target will also be cleared.

Visszatérési érték

Returns true if the render target was successfully changed, false otherwise.

Usage restrictions

Items drawn with postGUI set to true will not appear on a custom render target.

dxSetRenderTarget can be set at any time as long as <min_mta_version> in meta.xml is set to at least 1.3.0-9.04431 e.g. <min_mta_version client="1.3.0-9.04431" />

Példa

addEventHandler("onClientResourceStart", resourceRoot,
    function()
        myRenderTarget = dxCreateRenderTarget( 80, 100 )  -- Create a render target texture which is 80 x 100 pixels
    end
)

addEventHandler( "onClientRender", root,
    function()
        if myRenderTarget then
            dxSetRenderTarget( myRenderTarget )  -- Select custom render target
            dxDrawText ( "Hello", 10, 20 )       -- The message 'Hello' will be drawn on myRenderTarget

            dxSetRenderTarget()                  -- Select default render target
            dxDrawText ( "Goodbye", 10, 20 )     -- The message 'Goodbye' will be drawn directly to the screen
        end
    end
)

This example shows how you can prepare render target contents at anytime (from client version 1.3.0-9.04431)

addEventHandler("onClientResourceStart", resourceRoot,
    function()
        myRenderTarget = dxCreateRenderTarget( 80, 100 )     -- Create a render target texture which is 80 x 100 pixels
        dxSetRenderTarget( myRenderTarget )                  -- Select custom render target for drawing
        dxDrawRectangle ( 2, 2, 60, 60, tocolor(255,255,0) ) -- Draw anything you like (to the render target)
        dxDrawText ( "Hello", 10, 20 )
        dxDrawText ( "This is", 10, 40 )
        dxDrawText ( "Amazing", 10, 60 )
        dxSetRenderTarget()                                  -- Unselect custom render target
    end
)

addEventHandler( "onClientRender", root,
    function()
        if myRenderTarget then
            dxDrawImage ( 100, 200, 80, 100, myRenderTarget )        -- Draw myRenderTarget content to the screen
        end
    end
)
