Unstable tile
From SuperTux
Unstable tiles are a special kind of tile on which Tux can stand only for a limited time. After that, the block starts to dissolve and / or to fall down.
The sprites for unstable tiles may have four actions:
- normal
- Displayed until Tux steps on the tile.
- shake
- The tile shakes but is still solid.
- dissolve
- The tile is dissolving. After the animation for this action is done, the tile will be set non-solid.
- fall-down
- Gravity is enabled for this tile and it will begin to fall down.
Each of the actions shake, dissolve and fall-down is optional. If a sprite doesn't have the dissolve action, the till will still be solid when the fall-down action is executed (Donut Tile style). If the tile doesn't have a fall-down action, it will be removed after the dissolve animation is done (Giana Sisters style).
