◆ supportMultipleTextures()

bool Graphics::GraphicsManager::supportMultipleTextures ( ) const

Do we have support for multiple textures?

Definition at line 191 of file graphics.cpp.

References _supportMultipleTextures.

◆ takeScreenshot()

void Graphics::GraphicsManager::takeScreenshot ( )

Take a screenshot.

References _takeScreenshot, lockFrame(), and unlockFrame().

Here is the call graph for this function:

◆ unlockFrame()

void Graphics::GraphicsManager::unlockFrame ( )

Decrease the frame lock counter, potentially re-enabling frame rendering.

Whereas lockFrame() increases the frame lock counter, this method decreases it again. As soon as the frame lock counter reaches 0, i.e. the frame has been unlocked the same number of times it has been locked previously, all frame rendering is re-enabled.
