DrawableTexture2D

Hereda: Texture2D < Texture < Resource < RefCounted < Object

A 2D texture that supports drawing to itself via Blit calls.

Descripción

A 2D texture that can be modified via blit calls, copying from a target texture to itself. Primarily intended to be managed in code, a user must call setup() to initialize the state before drawing. Each blit_rect() call takes at least a rectangle, the area to draw to, and another texture, what to be drawn. The draw calls use a Texture_Blit Shader to process and calculate the result, pixel by pixel. Users can supply their own ShaderMaterial with custom Texture_Blit shaders for more complex behaviors.

Enumeraciones

enum DrawableFormat: 🔗

DrawableFormat DRAWABLE_FORMAT_RGBA8 = 0

OpenGL texture format RGBA with four components, each with a bitdepth of 8.

DrawableFormat DRAWABLE_FORMAT_RGBA8_SRGB = 1

OpenGL texture format RGBA with four components, each with a bitdepth of 8.

When drawn to, an sRGB to linear color space conversion is performed.

DrawableFormat DRAWABLE_FORMAT_RGBAH = 2

OpenGL texture format GL_RGBA16F where there are four components, each a 16-bit "half-precision" floating-point value.

DrawableFormat DRAWABLE_FORMAT_RGBAF = 3

OpenGL texture format GL_RGBA32F where there are four components, each a 32-bit floating-point value.

Descripciones de Métodos

void blit_rect(rect: Rect2i, source: Texture2D, modulate: Color = Color(1, 1, 1, 1), mipmap: int = 0, material: Material = null) 🔗

Experimental: Este método podría ser modificado o eliminado en versiones futuras.

Draws to given rect on this texture by copying from the given source. A modulate color can be passed in for the shader to use, but defaults to White. The mipmap value can specify a draw to a lower mipmap level. The material parameter can take a ShaderMaterial with a TextureBlit Shader for custom drawing behavior.

---

void blit_rect_multi(rect: Rect2i, sources: Array[Texture2D], extra_targets: Array[DrawableTexture2D], modulate: Color = Color(1, 1, 1, 1), mipmap: int = 0, material: Material = null) 🔗

Experimental: Este método podría ser modificado o eliminado en versiones futuras.

Draws to the given rect on this texture, as well as on up to 3 DrawableTexture extra_targets. All extra_targets must be the same size and DrawableFormat as the original target, otherwise the Shader may fail. Expects up to 4 Texture sources, but will replace missing sources with default Black Textures.

---

void generate_mipmaps() 🔗

Re-calculates the mipmaps for this texture on demand.

---

bool get_use_mipmaps() const 🔗

Returns true if mipmaps are set to be used on this DrawableTexture.

---

void set_format(format: DrawableFormat) 🔗

Sets the format of this DrawableTexture.

---

void set_use_mipmaps(mipmaps: bool) 🔗

Sets if mipmaps should be used on this DrawableTexture.

---

void setup(width: int, height: int, format: DrawableFormat, color: Color = Color(1, 1, 1, 1), use_mipmaps: bool = false) 🔗

Experimental: Este método podría ser modificado o eliminado en versiones futuras.

Initializes the DrawableTexture to a White texture of the given width, height, and format.
