* oslSetChannelVolume removed (set the sound's volume itself instead, that is OSL_SOUND->volumeLeft /volumeRight = ...). Should simplify your code. | * oslSetChannelVolume removed (set the sound's volume itself instead, that is OSL_SOUND->volumeLeft /volumeRight = ...). Should simplify your code. | ||
* Untextured geometry colors are now blended, taking in account the oslSetAlpha values. If you did blend by yourself, remove your code. If you expected them to be drawn directly (opaque), you'll have to disable alpha before drawing them, just like you would have done with an image. A deprecated trick is to set osl_currentAlphaCoeff to 0xffffffff but it's not very reliable and not assured to work in the future (and will mess up oslGetAlphaEx and so on). | * Untextured geometry colors are now blended, taking in account the oslSetAlpha values.

* oslLoadImageFile will not read images if the extension is not .png (or .gif or .jpg). If you've renamed your files, this will not work anymore. Please use oslLoadImageFilePNG instead. | * oslLoadImageFile will not read images if the extension is not .png (or .gif or .jpg). If you've renamed your files, this will not work anymore.

* Use oslSetDithering rather than sceGuEnable(GU_DITHER), it's cleaner as it stores the current state so that you can retreive it. | * Use oslSetDithering rather than sceGuEnable(GU_DITHER), it's cleaner as it stores the current state so that you can retreive it. | ||
