Method Detail

bgfx_render_frame

public static int bgfx_render_frame(int _msecs)

Render frame.

bgfx_render_frame is blocking call. It waits for frame to be called from API thread to process frame. If timeout value is passed call will timeout and return even if bgfx_frame is not called.

This call should be only used on platforms that don't allow creating separate rendering thread. If it is called before to init, render thread won't be created by init call.

Parameters:

_msecs - timeout in milliseconds

Returns:

current renderer state. One of: RENDER_FRAME_NO_CONTEXT RENDER_FRAME_RENDER RENDER_FRAME_TIMEOUT RENDER_FRAME_EXITING RENDER_FRAME_COUNT

nbgfx_set_platform_data

public static void nbgfx_set_platform_data(long _data)

Unsafe version of: set_platform_data

bgfx_set_platform_data

public static void bgfx_set_platform_data(BGFXPlatformData _data)

Sets platform data.

Must be called before init.

Parameters:

_data - the platform data to set

nbgfx_get_internal_data

public static long nbgfx_get_internal_data()

Unsafe version of: get_internal_data

bgfx_get_internal_data

@Nullable
public static BGFXInternalData bgfx_get_internal_data()

Gets internal data for interop.

bgfx_override_internal_texture_ptr

public static long bgfx_override_internal_texture_ptr(short _handle,
                                                      long _ptr)

Overrides internal texture with externally created texture. Previously created internal texture will released.

It's expected you understand some bgfx internals before you use this call.

Must be called only on render thread.

Parameters:

_handle - texture handle

_ptr - native API pointer to texture

Returns:

native API pointer to texture. If result is 0, texture is not created yet from the main thread.

nbgfx_override_internal_texture

public static long nbgfx_override_internal_texture(short _handle,
                                                   short _width,
                                                   short _height,
                                                   byte _numMips,
                                                   int _format,
                                                   long _flags)

Unsafe version of: override_internal_texture

bgfx_override_internal_texture

public static long bgfx_override_internal_texture(short _handle,
                                                  int _width,
                                                  int _height,
                                                  int _numMips,
                                                  int _format,
                                                  long _flags)

Overrides internal texture by creating new texture. Previously created internal texture will released.

It's expected you understand some bgfx internals before you use this call.

Must be called only on render thread.

Parameters:

_handle - texture handle

_width - width

_height - height

_numMips - number of mip-maps

_format - texture format

_flags - default texture sampling mode is linear, and wrap mode is repeat

Returns:

native API pointer to texture. If result is 0, texture is not created yet from the main thread.
