Texture for 2D and 3D.

描述

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.

Method Descriptions

void _draw ( RID to_canvas_item, Vector2 pos, Color modulate, bool transpose ) virtual const

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_rect ( RID to_canvas_item, Rect2 rect, bool tile, Color modulate, bool transpose ) virtual const

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_region ( RID to_canvas_item, Rect2 rect, Rect2 src_rect, Color modulate, bool transpose, bool clip_uv ) virtual const

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.


int _get_height ( ) virtual const

Called when the Texture2D's height is queried.


int _get_width ( ) virtual const

Called when the Texture2D's width is queried.


bool _has_alpha ( ) virtual const

Called when the presence of an alpha channel in the Texture2D is queried.


bool _is_pixel_opaque ( int x, int y ) virtual const

Called when a pixel's opaque state in the Texture2D is queried at the specified (x, y) position.


Resource create_placeholder ( ) const

Creates a placeholder version of this resource (PlaceholderTexture2D).


void draw ( RID canvas_item, Vector2 position, Color modulate=Color(1, 1, 1, 1), bool transpose=false ) const

Draws the texture using a CanvasItem with the RenderingServer API at the specified position.


void draw_rect ( RID canvas_item, Rect2 rect, bool tile, Color modulate=Color(1, 1, 1, 1), bool transpose=false ) const

Draws the texture using a CanvasItem with the RenderingServer API.


void draw_rect_region ( RID canvas_item, Rect2 rect, Rect2 src_rect, Color modulate=Color(1, 1, 1, 1), bool transpose=false, bool clip_uv=true ) const

Draws a part of the texture using a CanvasItem with the RenderingServer API.


int get_height ( ) const

Returns the texture height in pixels.


Image get_image ( ) 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 fetch the texture data from the GPU, which might cause performance problems when overused.


Vector2 get_size ( ) const

Returns the texture size in pixels.


int get_width ( ) const

Returns the texture width in pixels.


bool has_alpha ( ) const

Returns true if this Texture2D has an alpha channel.
