Swapped the water's disableTrueReflections variable to be enableTrueReflections for simplicity and consistency(also fixed a persistent typo) Swapped disableVerticalSync to be enableVerticalSync for simplicity and consistency Swapped disableParallaxMapping to be enableParallaxMapping for simplicity and consistency Fix click detection on slider mode entries for guiGameSettingsCtrl so the click position correctly matches the percentage Fixed problem where postFX initialization would always exec default.postfxpreset.tscript, even if a level's got it's own preset, which can cause problems Fixed range field type behavior so that editing the values applies in real time, and also consistently applies between slider and text field

/// GFXDevice is the TSE graphics interface layer. This allows the TSE to
|
|
/// do many things, such as use multiple render devices for multi-head systems,
|
|
/// and allow a game to render in DirectX 9, OpenGL or any other API which has
|
|
/// a GFX implementation seamlessly. There are many concepts in GFX device which
|
|
/// may not be familiar to you, especially if you have not used DirectX.
|

/// @n
|
|
/// <b>Buffers</b>
|
|
/// There are three types of buffers in GFX: vertex, index and primitive. Please
|
|
/// note that index buffers are not accessable outside the GFX layer, they are wrapped
|
|
/// by primitive buffers. Primitive buffers will be explained in detail later.
|
|
/// Buffers are allocated and deallocated using their associated allocXBuffer and
|
|
/// freeXBuffer methods on the device. When a buffer is allocated you pass in a
|
|
/// pointer to, depending on the buffer, a vertex type pointer or a U16 pointer.
|
|
/// During allocation, this pointer is set to the address of where you should
|
|
/// copy in the information for this buffer. You must the tell the GFXDevice
|
|
/// that the information is in, and it should prepare the buffer for use by calling
|
|
/// the prepare method on it. Dynamic vertex buffer example:
|
|
/// @code
|
|
/// GFXVertexP *verts; // Making a buffer containing verticies with only position
|
|
///
|
|
/// // Allocate a dynamic vertex buffer to hold 3 vertices and use *verts as the location to copy information into
|
|
/// GFXVertexBufferHandle vb = GFX->allocVertexBuffer( 3, &verts, true );
|
|
///
|
|
/// // Now set the information, we're making a triangle
|
|
/// verts[0].point = Point3F( 200.f, 200.f, 0.f );
|
|
/// verts[1].point = Point3F( 200.f, 400.f, 0.f );
|
|
/// verts[2].point = Point3F( 400.f, 200.f, 0.f );
|
|
///
|
|
/// // Tell GFX that the information is in and it should be made ready for use
|
|
/// // Note that nothing is done with verts, this should not and MUST NOT be deleted
|
|
/// // stored, or otherwise used after prepare is called.
|
|
/// GFX->prepare( vb );
|
|
///
|
|
/// // Because this is a dynamic vertex buffer, it is only assured to be valid until someone
|
|
/// // else allocates a dynamic vertex buffer, so we will render it now
|
|
/// GFX->setVertexBuffer( vb );
|
|
/// GFX->drawPrimitive( GFXTriangleStrip, 0, 1 );
|
