Struct mage_core::app::PresentInput

pub struct PresentInput<'textures> {
    pub width: u32,
    pub height: u32,
    pub fore_image: &'textures mut [u32],
    pub back_image: &'textures mut [u32],
    pub text_image: &'textures mut [u32],
}

The PresentInput struct is passed to the [present] method of the App trait to provide information about the current frame.

Fields

width: u32

The width of the window in characters.

height: u32

The height of the window in characters.

fore_image: &'textures mut [u32]

The foreground color of each character. Each 32-bit RGBA value represents a single character. The least significant 8 bits are the red value, the next 8 bits are the green value, the next 8 bits are the blue value, and the most significant 8 bits are the alpha value. The alpha value is currently unused.

back_image: &'textures mut [u32]

The background color of each character. Each 32-bit RGBA value represents a single character. The least significant 8 bits are the red value, the next 8 bits are the green value, the next 8 bits are the blue value, and the most significant 8 bits are the alpha value. The alpha value is currently unused.

text_image: &'textures mut [u32]

The character buffer. Each 32-bit RGBA value represents a single character. The least significant 8 bits are the ASCII value of the character, and the most significant 24 bits are unused by the engine but are available for use by the game.

Implementations

impl<'t> PresentInput<'t>

pub fn rect(&self) -> Rect

pub fn new_image(&self) -> Image

pub fn blit( &mut self, dst_rect: Rect, src_rect: Rect, src_image: &Image, paper: u32 )

Blit the an area of the source image to the screen.

The source rectangle is clipped to the source image.

Arguments

• dst_rect - Where to blit the source image to on the screen.
• src_rect - The area of the source image to blit.
• src_image - The source image to blit from.
• paper - The paper colour to use outside the source image. This will also be used as the ink colour.

pub fn clear(&mut self, rect: Rect, paper: u32)

pub fn blit_internal( &mut self, dst_rect: Rect, src_rect: Rect, src_image: &Image )

Trait Implementations

impl<'textures> Debug for PresentInput<'textures>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'textures> PartialEq for PresentInput<'textures>

fn eq(&self, other: &PresentInput<'textures>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
