au3Irr2 Function Reference
_IrrSetTextureCreationFlagSets texture creation flags controlling how textures are handled when they are created.
#Include <au3Irrlicht2.au3>
_IrrSetTextureCreationFlag($i_Flag, $i_Value)
Parameters
| $i_Value | The following flags can be set; $ETCF_ALWAYS_16_BIT - Forces the driver to always create 16 bit textures, independently of which format the file on disk has. $ETCF_ALWAYS_32_BIT - Forces the driver to always create 32 bit textures, independently of which format the file on disk has. $ETCF_OPTIMIZED_FOR_QUALITY - Lets the driver decide in which format the textures are created and tries to make the textures look as good as possible. $ETCF_OPTIMIZED_FOR_SPEED - Lets the driver decide in which format the textures are created and tries to create them maximizing render speed. $ETCF_CREATE_MIP_MAPS - Automatically creates mip map levels for the textures. $ETCF_NO_ALPHA_CHANNEL - Discard any alpha layer and use non-alpha color format. |
| $i_Flag | Turn Creation Flag Off or On ($IRR_OFF or $IRR_ON) |
Return Value
Success: TrueFailure: False

Example
#include <au3Irrlicht2.au3>
Global $hTexture, $aInfo
_IrrStart()
; Set the Texture creation flag to load textures in 16 bit without alpha (R5G6B5 format)
_IrrSetTextureCreationFlag( BitOR($ETCF_ALWAYS_16_BIT, $ETCF_NO_ALPHA_CHANNEL), $IRR_ON )
; Load a texture
$hTexture = _IrrGetTexture("./media/cross.bmp")
; query some info about the loaded texture, index 3 of the returned array is Color Reference
$aInfo = _IrrGetTextureInformation($hTexture)
; show the color format in a string to see the Texture creation flag was set
MsgBox(64, "Texture color format", _TextureFormatString($aInfo[3]))
