cubos::engine::RenderPicker struct
#include <engine/render/picker/picker.hpp>

Component which provides a texture to store entity/gizmo ids, for selection with a mouse.

Public functions

auto read(unsigned int x, unsigned int y) const -> uint32_t: Reads the identifier at the given pixel coordinates.

glm::uvec2 size: Size of the RenderPicker textures, in pixels.
bool cleared: Whether the RenderPicker front texture has already been cleared this frame.
core::gl::Texture2D backTexture: Picking back texture, stores entity/gizmo ids for each pixel on the screen. Access to the picker results is made through this texture, to ensure the CPU doesn't wait for the current frame to finish.
core::gl::Texture2D frontTexture: Picking front texture, stores entity/gizmo ids for each pixel on the screen. This is the texture used by the renderer to write ids. It is automatically swapped with the back texture by the renderPickerPlugin.
core::gl::PixelPackBuffer pixelBuffer: Pixel pack buffer used to access the data in the backTexture.

Reads the identifier at the given pixel coordinates.
