Editing Tile Layers
===================

:ref:`tile-layer-introduction` are what makes Tiled a *tile map editor*.
Although not as flexible as :ref:`object-layer-introduction`, they provide
efficient data storage and good rendering performance as well as efficient
content creation. Every new map gets one by default, though feel free to delete
it when you're not going to use it.

.. _stamp-tool:

Stamp Brush
-----------

Shortcut: ``B``

The primary tool for editing tile layers is the Stamp Brush. It can be
used to paint single tiles as well as larger "stamps", which is where it
gets its name from. Using the right mouse button, it can also quickly
capture tile stamps from the currently active layer. A tile stamp is
commonly created by selecting one or more tiles in the Tilesets view.

The Stamp Brush has some extra features:

-  While holding ``Shift``, click any two points to draw a line between
   them.

-  While holding ``Ctrl+Shift``, click any two points two draw a circle
   or ellipse centered on the first point.

-  Activate the *Random Mode* using the dice button on the Tool Options
   toolbar to have the Stamp Brush paint with random tiles from the tile
   stamp. The probability of each tile depends on how often it occurred
   on the tile stamp, as well as the probability set on each tile in the
   *Tileset Editor*.

-  Activate the *Wang Fill Mode* using the Wang tile button on the tool bar
   to have the Stamp Brush paint using the Wang methods. This makes adjacent
   tiles match edge and corner colors to be placed. Wang tiles are described
   in detail in :doc:`using-wang-tiles`.

-  In combination with the *Tile Stamps* view, it can also place
   randomly from a set of predefined tile stamps. This can be more
   useful than the *Random Mode*, which randomly places individual
   tiles.

-  You can flip the current tile stamp horizontally/vertically by using
   ``X`` and ``Y`` respectively. You can also rotate left/right by
   using ``Z`` and ``Shift+Z`` respectively. These actions can also be
   triggered from the Tool Options tool bar.

.. _terrain-tool:

Terrain Brush
-------------

Shortcut: ``T``

The Terrain Brush allows for efficient editing with a certain type of
corner-based terrain transitions. Setting it up requires associating
terrain information with your tiles, which is described in detail in
:doc:`Using the Terrain Tool <using-the-terrain-tool>`.

Similarly to the :ref:`stamp-tool`, you can draw lines by holding
``Shift``. When holding ``Ctrl``, the size of the editing area is
reduced to one corner (this currently doesn't work well in combination
with drawing lines).

.. raw:: html

   <div class="new new-prev">Since Tiled 1.0</div>

When holding ``Alt``, the editing operations are also applied at a 180
degree rotation. This is especially useful when editing strategic maps
where two sides need to have equal opportunities. The modifier works
well in combination with either ``Shift`` for drawing lines or ``Ctrl``
for reducing the edited area.

.. raw:: html

   <div class="new new-prev">Since Tiled 1.1</div>

.. _wang-tool:

Wang Brush
----------

Shortcut: ``G``

The Wang Brush works in a very similar way to the :ref:`terrain-tool`, except
it uses Wang sets. Key differences are:

-  Wang tiles support edges as well as corners, whereas terrains only support
   corners. This makes Wang tiles useful for drawing paths, or fences.
-  The default size is to edit one edge/corner. Holding ``Ctrl`` expands it
   to the whole tile.
-  If the transition cannot be made on the immediately affected tiles,
   the operation is aborted.

To use the tool, a color must be selected from the Wang color view.
Wang tiles and this tool are described in detail in :doc:`using-wang-tiles`.

.. _bucket-fill-tool:

Bucket Fill Tool
----------------

Shortcut: ``F``

The Bucket Fill Tool provides a quick way of filling empty areas or
areas covered with the same tiles. The currently active tile stamp will
be repeated in the filled area. It can also be used in combination with
the *Random Mode*, or *Wang Fill Mode*.

When holding ``Shift``, the tool fills the currently selected area
regardless of its contents. This is useful for filling custom areas that
have been selected previously using one or more `Selection
Tools <#selection-tools>`__.

You can also flip and rotate the current stamp as described for the
:ref:`stamp-tool`.

.. raw:: html

   <div class="new new-prev">Since Tiled 1.1</div>

.. _shape-fill-tool:

Shape Fill Tool
---------------

Shortcut: ``P``

This tool provides a quick way to fill rectangles or ellipses with a certain
tile or pattern. Hold ``Shift`` to fill an exact square or circle.

You can also flip and rotate the current stamp as described for the
:ref:`stamp-tool`.

.. _eraser-tool:

Eraser
------

Shortcut: ``E``

A simple eraser tool. Left click erases single tiles and right click can
be used to quickly erase rectangular areas.

Selection Tools
---------------

There are various tile selection tools that all work in similar fashion:

-  **Rectangular Select** allows selection of rectangular areas
   (shortcut: ``R``)

-  **Magic Wand** allows selection of connected areas filled with the
   same tile (shortcut: ``W``)

-  **Select Same Tile** allows selection of same-tiles across the entire
   layer (shortcut: ``S``)

By default, each of these tools replaces the currently selected area.
The following modifiers can be used to change this behavior:

-  Holding ``Shift`` expands the current selection with the new area
-  Holding ``Ctrl`` subtracts the new area from the current selection
-  Holding ``Ctrl`` and ``Shift`` selects the intersection of the new
   area with the current selection

You can also lock into one of these modes (Add, Subtract or Intersect)
by clicking on one of the tool buttons in the Tool Options toolbar.

Managing Tile Stamps
--------------------

It can often be useful to store the current tile stamp somewhere to use
it again later. The following shortcuts work for this purpose:

-  ``Ctrl + 1-9`` - Store current tile stamp (similar to ``Ctrl + C``)
-  ``1-9`` - Recall the stamp stored at this location (similar to
   ``Ctrl + V``)

Tile stamps can also be stored by name and extended with variations
using the *Tile Stamps* view.
