Class Texture2D
Texture for 2D and 3D.
- Inheritance
-
Texture2D
- Derived
Remarks
A texture works by registering an image in the video hardware, which then can be used in 3D models or 2D Sprite2D or GUI Control.
Textures are often created by loading them from a file. See @GDScript.load.
Texture2D is a base for other resources. It cannot be used directly.
Note: The maximum texture size is 16384×16384 pixels due to graphics hardware limitations. Larger textures may fail to import.
Methods
_draw(RID, Vector2, Color, bool)
Qualifiers: virtualconst
Called when the entire Texture2D is requested to be drawn over a CanvasItem, with the top-left offset specified in pos
. modulate
specifies a multiplier for the colors being drawn, while transpose
specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).
Note: This is only used in 2D rendering, not 3D.
void _draw(RID to_canvas_item, Vector2 pos, Color modulate, bool transpose)
Parameters
_draw_rect(RID, Rect2, bool, Color, bool)
Qualifiers: virtualconst
Called when the Texture2D is requested to be drawn onto CanvasItem's specified rect
. modulate
specifies a multiplier for the colors being drawn, while transpose
specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).
Note: This is only used in 2D rendering, not 3D.
void _draw_rect(RID to_canvas_item, Rect2 rect, bool tile, Color modulate, bool transpose)
Parameters
_draw_rect_region(RID, Rect2, Rect2, Color, bool, bool)
Qualifiers: virtualconst
Called when a part of the Texture2D specified by src_rect
's coordinates is requested to be drawn onto CanvasItem's specified rect
. modulate
specifies a multiplier for the colors being drawn, while transpose
specifies whether drawing should be performed in column-major order instead of row-major order (resulting in 90-degree clockwise rotation).
Note: This is only used in 2D rendering, not 3D.
void _draw_rect_region(RID to_canvas_item, Rect2 rect, Rect2 src_rect, Color modulate, bool transpose, bool clip_uv)
Parameters
_get_height
Qualifiers: virtualconst
Called when the Texture2D's height is queried.
int _get_height
_get_width
Qualifiers: virtualconst
Called when the Texture2D's width is queried.
int _get_width
_has_alpha
Qualifiers: virtualconst
Called when the presence of an alpha channel in the Texture2D is queried.
bool _has_alpha
_is_pixel_opaque(int, int)
Qualifiers: virtualconst
Called when a pixel's opaque state in the Texture2D is queried at the specified (x, y)
position.
bool _is_pixel_opaque(int x, int y)
Parameters
create_placeholder
Qualifiers: const
Creates a placeholder version of this resource (PlaceholderTexture2D).
Resource create_placeholder
draw(RID, Vector2, Color, bool)
Qualifiers: const
Draws the texture using a CanvasItem with the RenderingServer API at the specified position
.
void draw(RID canvas_item, Vector2 position, Color modulate, bool transpose)
Parameters
draw_rect(RID, Rect2, bool, Color, bool)
Qualifiers: const
Draws the texture using a CanvasItem with the RenderingServer API.
void draw_rect(RID canvas_item, Rect2 rect, bool tile, Color modulate, bool transpose)
Parameters
draw_rect_region(RID, Rect2, Rect2, Color, bool, bool)
Qualifiers: const
Draws a part of the texture using a CanvasItem with the RenderingServer API.
void draw_rect_region(RID canvas_item, Rect2 rect, Rect2 src_rect, Color modulate, bool transpose, bool clip_uv)
Parameters
get_height
Qualifiers: const
Returns the texture height in pixels.
int get_height
get_image
Qualifiers: const
Returns an Image that is a copy of data from this Texture2D (a new Image is created each time). Images can be accessed and manipulated directly.
Note: This will return null
if this Texture2D is invalid.
Note: This will fetch the texture data from the GPU, which might cause performance problems when overused. Avoid calling get_image every frame, especially on large textures.
Image get_image
get_size
Qualifiers: const
Returns the texture size in pixels.
Vector2 get_size
get_width
Qualifiers: const
Returns the texture width in pixels.
int get_width
has_alpha
Qualifiers: const
Returns true
if this Texture2D has an alpha channel.
bool has_alpha
