## Detailed Description

Sprites pool class automates processing of several sprites. It remembers pointers to SPRITE objects, and carefully updates only the areas, touched by the sprites. So, it reduces number of i2c calls to SSD1306 display.

Warning
  this class is deprecated and not supported anymore.

Deprecated:
  use NanoEngine, NanoSprite objects.

## Constructor & Destructor Documentation

## ◆ SpritePool()

SpritePool::SpritePool | ( |  | ) |

Creates empty SpritePool object. It is able to hold up to 10 sprites on AVR platforms and up to 32 sprites on ESP platforms.

## Member Function Documentation

## ◆ add()

uint8_t SpritePool::add | ( | SPRITE & | sprite | ) |

Adds SPRITE object to the internal list of SpritePool

Parameters

  sprite | - reference to SPRITE object

Returns
  index of added object or SP_ERR_NO_SPACE in case of error.

## ◆ clear()

void SpritePool::clear | ( |  | ) |

Removes all SPRITE objects from internal list of SpritePool.

## ◆ drawBlock()

virtual void SpritePool::drawBlock | ( | uint8_t | blockColumn,
|  | uint8_t | blockRow
| ) |  |
| protected virtual

This method is call every time 8x8 pixels block is needed to be drawn. Use m_canvas field variable, which represents block to update. For example, you can draw any 8x8 image, starting at 0,0 position in m_canvas.

Parameters

  blockColumn | - column of the block to redraw
  blockRow | - row of the block to redraw

Note
  128x64 display has 16 columns and 8 rows.

## ◆ drawSprites()

void SpritePool::drawSprites | ( |  | ) |

Draw all areas, touched by the sprites. To remove flickering, the method uses NanoCanvas capabilities.

## ◆ refreshScreen()

void SpritePool::refreshScreen | ( |  | ) |

Redraws whole area, used by the sprites.

## ◆ remove()

void SpritePool::remove | ( | SPRITE & | sprite | ) |

Removes specific SPRITE object from the SpritePool.

## ◆ setRect()

void SpritePool::setRect | ( | SSD1306_RECT | rect | ) |
| inline

Sets active paint area region in blocks (pixels / 8)

Parameters

  rect | - region in blocks (pixels / 8)
