Step 1

Select your sprite GameObject, and find the SpriteRenderer component in the Inspector tab.

Then, open its context menu (the ⋮ button), and select the Make Paintable (Paint in 2D) option.

This will add the CwPaintableSprite and CwPaintableSpriteTexture components to it.

Step 2

Make a new GameObject, and add the CwHitScreen2D and CwPaintDecal2D components.

When combined, these components allow you to paint to all paintable sprites in your scene.

Feel free to adjust the CwPaintDecal2D component's settings like Texture, Color, etc.

Step 3 - Done!

You can now hit the ▶ Play button, and enjoy painting your sprite.

You can also make a build for mobile and paint with your fingers.

You can now go through all the tutorial demo scenes in the Plugins/CW/PaintIn2D/Examples folder. These take you step by step through every feature of this asset, and the description text shows you exactly what is being shown.

Make Paintable

This shows you how to configure a sprite for painting. First, select your Sprite GameObject, and in the inspector open the Sprite Renderer component's context menu (the ⋮ button), and select the \"Make Paintable (Paint in 2D)\" option. Next, add a 2D collider to it, like the PolygonCollider2D. Once done, it should look like the \"Paintable Book\" GameObject in this scene.

Texture Painting

This shows you how to paint sprites. First, make a new GameObject, and add the CwHitScreen2D component. This will automatically add the CwPointerMouse, CwPointerTouch, and CwPointerPen components, which add painting support for mouse, touch, and tablet pens. Next, you can add the CwPaintDecal2D component, and set its Texture and Color settings as desired. The \"Paint Texture\" GameObject is an example of what this might look like.

Modifiers

This shows you how the CwPaintDecal2D component's Modifier system can be used to make the painted texture look more interesting. Simply click the \"Add Modifier\" button, and choose what you would like to modify. In this scene the \"Paint Texture\" GameObject has modifiers that randomize the angle, color, and radius of the painted texture.

Tools

This shows you how to quickly make a selection of painting tools that can be chosen using the UI. This is done by adding many painting GameObjects to the Tools GameObject. Each tool has the CwDemoButtonBuilder component, and once configured you can press the BuildAll button, where it add buttons to your UI that allows you to choose between them.

Atlas

This shows you what happens when you try to paint a sprite that's part of an atlas (if you have the Sprite Packer setting enabled). You can see that it works, but the painting resolution is reduced. This is because a texture atlas is usually high resolution, but the painting resolution is usually lower. While you can adjust the CwPaintableSpriteTexture component's Size setting to account for this - It's recommend that you remove your paintable sprites from atlases. This is because each paintable sprite has its own unique paint state, so they're not batched together, and therefore you get no benefit from putting these specific paintable sprites in an atlas.

Atlas Overlay

This shows you how high resolution painting can still be achieved with texture atlases. This is done by adding a secondary sprite on top of your atlas which is configured for painting. This allows the underlying sprite to be high resolution and part of an atlas, and the actual overlay paint sprite to be entirely separate and at a different resolution. Keep in mind the overlay sprite must not be in an atlas. Also keep in mind you must set the CwPaintableSpriteTexture.Color setting to be transparent (0 alpha/opacity). Also keep in mind you must adjust the sprite's Additional Settings / OrderInLayer or Z position so it renders on top of the base sprite.

Local Mask

This shows you how the CwPaintableSpriteTexture component's Advanced/LocalMask setting can be used to restrict painting to specific areas of your sprite. Keep in mind the mask texture must be the same size as the base sprite.

Change Counter

This shows you how the CwChangeCounter component can be used to count how many pixels of a sprite are different relative to the original sprite. This is shown in the UI using the CwChangeCounterFill and CwChangeCounterText and CwChangeCounterEvent components.

Color Counter

This shows you how the CwColorCounter component can be used to count how many pixels of a sprite match specific colors. Each color is defined using the CwColor component, which you can see are children of the Colors GameObject. The color counts are shown in the UI using the CwColorCounterFill and CwColorCounterText and CwColorCounterEvent components.

Collision Painting

This shows you how the CwHitCollisions2D and CwPaintDecal2D components can be used to apply paint at the contact point between the current sprite and another.

Continuous Collision Painting

This shows you how multiple CwHitCollisions2D components can be used at the same time. This is done by placing the CwPaintDecal2D components in child GameObject, and dragging and dropping them into the CwHitCollisions2D component's Advanced/Root setting. You can also disable the OnlyUseFirstContact setting to make it continuously apply paint as it collides.

Undo Redo

This shows you how the CwPaintableSpriteTexture component's UndoRedo setting can be enabled. You can then make UI images with the CwButtonUndoAll and CwButtonRedoAll component to turn them into buttons.

Clear

This shows you how paint can be reset by adding the CwButtonClearAll component to your UI images to turn them into buttons.

Save Load

This shows you how paint can be automatically saved and loaded by setting the CwPaintableSpriteTexture component's SaveLoad setting to Automatic, and setting a name for this sprite's save data. The sprite's paint will then be automatically saved/loaded when you start/stop the scene or run the app.

Decal Sticker

This shows you how to paint decals like stickers. This is done by changing the CwHitScreen2D component's Frequency setting can be set to Once On Release, and enabling the CwPointerMouse component's Preview setting.

Paint Texture

This shows you how the CwPaintDecal2D component's Advanced / TileTexture setting can be used to paint a seamless texture with the decal shape. The TileTransform setting can also be used to control the tiling and rotation of the tiled texture.

Dotted Lines

This shows you how the CwHitScreen2D component's Frequency setting can be set to PixelInterval or ScaledPixelInterval (DPI independent). This then allows you to set the Interval setting, which allows you to draw a dotted line as your mouse/finger drags across the screen.

Straight Lines

This shows you how instead of the CwHitScreen2D component, the CwHitScreenLine2D can be used. This allows you to draw lines between the start and end positions of a finger swipe. This component's Frequency setting can be used to control how many points are in the line relative to its length. This component's Advanced/ConnectHits and Advanced/ClipConnected settings can be enabled to make a solid line.

Eraser

This shows you how a sprite's texture can be erased/restored to its original state. To erase it, the paint tool's CwPaintDecal2D component's BlendMode setting can be set to ReplaceOriginal. This will paint the sprite back to its original state.

Erase Alpha & Restore Alpha

This shows you how a sprite's alpha can be erased and restored. To erase it, the paint tool's CwPaintDecal2D component's BlendMode setting can be set to Subtractive, with a Channels setting of 0,0,0,1, so it only subtracts the alpha/opacity. To restore it, the ReplaceOriginal blending mode can be used, with the same 0,0,0,1 Channels setting.

Reveal From Invisible

This shows you how to initialize a sprite as transparent, and then paint the alpha back to restore it. This is done by changing the paintable sprite texture component's Color setting to have 0 alpha/opacity. This means when activated, the sprite will become invisible. The alpha can then be restored with your painting tool's CwPaintDecal2D component's BlendMode setting set to ReplaceOriginal, and the Channels set to 0,0,0,1, so it only replaces the alpha.

Stencil Mask

This shows you how the CwMaskSprite component can be added to a sprite, causing it to block all paint that hits the solid parts. Keep in mind only the closest mask will be used when painting. Keep in mind the CwDragToMove component used in this scene requires there to be a collider on your sprite.

Mirror Symmetry

This shows you how the CwCloneMirror component can be added to the scene, and it will cause all paint to be mirrored across the axis you can see in the Scene view. Keep in mind you must rotate it Y = 90 degrees initially. You can then adjust the X rotation.

Mirror Symmetry Flip

This shows you how the CwCloneMirror component's Flip setting can be enabled. This is useful if you want to mirror text, and other sprites that require the original orientation to be retained.

Color Picker

This shows you how the CwTapToReadColor component can be added to a sprite, allowing you to read its colors, and sending that color out via event. Keep in mind your sprite must have a 2D collider, and your camera must have the Physics2DRaycaster component. Keep in mind your sprite must have its Advanced/ReadWrite setting enabled, must have its Compression setting disabled, and it must not be in an atlas.

Particle Painting

This shows you how a particle system can be made to paint sprites on collision. First, on the particle system you must set Collision = true, then you must set Mode = 2D, and then you must set SendCollisionMessages = true. You can then add the CwHitParticles2D and CwPaintDecal2D components alongside, which will then paint the scene each time a particle hits something.

Paint Under

This shows you how the CwHitNearby and CwPaintDecal2D components can be combined to emit paint from a GameObject. If the CwHitNearby component's PaintIn is set to Update, then it will continuously paint. You can see a preview of what the paint shape looks like in the Scene tab.

Paint Under Tap

This shows you how to make a sprite paint a decal when you tap on it. This is done using the CwHitNearby and CwPaintDecal2D components, and setting the CwHitNearby component's PaintIn setting to ManuallyOnly. You can then add the CwTapEvent, and connect its event to the CwHitNearby component's ManuallyHitNow event, which will trigger it to paint each time you tap. Keep in mind the CwTapEvent and CwDragToMove components used in this scene require there to be a collider on your sprite.

Blur painting

This shows you how the CwPaintDecal2D component's BlendMode can be set to Blur. This causes all painted pixel to blur with their surrounding pixels. The Kernel setting can be used to control the range of the blur.

Flow Painting

This shows you how the CwPaintDecal2D component's BlendMode can be set to Flow. This allows you to set a tangent-space normal map texture in the Texture setting, which causes the painted pixels to flow in specific directions to create interesting effects.

Clone Stamp

This shows you how to create a clone stamp effect. This is done by adding an orthographic camera to your scene, and setting its TargetTexture to a RenderTexture asset in your project. The camera will then update the texture with what it sees in the scene, and you can drag and drop this texture into your CwPaintDecal2D component's Texture, which allows you to then paint it on your sprites.

Gradually Fade

This shows you how the CwGraduallyFade component can be used to slowly fade a sprite back to its original state, erasing all paint.

Gradually Appear

This shows you how to make paint gradually appear. This is done by creating two CwPaintableSpriteTexture components - one for the future, and one for the present. The future one is what is painted, and its Advanced/IsDummy setting must be enabled, so it doesn't get applied to your sprite. Your current texture must have its Group set to DUMMY, so that it doesn't get painted. The CwGraduallyFade component is then used to fade the current texture to the future one using BlendMode = Replace, and the future texture set in the BlendPaintableTexture setting.
