Creating Graphics

Download Article

1. 
   1
   Understand the two types of graphics. Video game design uses two types of graphic images, sprites and backdrops. Scratch has a variety of premade sprites and backdrops you can choose from. You can also make your own graphics inside of Scratch or using an external graphics editor.

   • Backdrops: Backdrops set the scene that your game takes place in. They are generally static images that take up the entire screen or play area. Click the icon that resembles a photograph in the lower-right corner to view a list of pre-made backgrounds. Click a backdrop image to select it.
   • Sprites: Sprites are objects that go on top of the background. They can be a playable character, non-playable characters, enemies and obstacles, power-ups, or other interactive objects. To select a premade sprite, click the icon that resembles a cat in the lower-right corner to view a list of premade sprites. Then click a sprite you want to use. All sprites in your project are listed below the play area in the upper-left corner. To delete a sprite, click the icon

   Understand the two graphic formats. Scratch allows you to make 2D games. The two types of 2D graphics you can create are bitmap and vector images.

   • Bitmap: Bitmap images are made up of pixels. Bitmap graphics are not used that often. The downside is they tend to have a fixed size. Enlarging raster images can make them look pixelated or fuzzy. Bitmap file formats supported by Scratch include JPEG/JPG, GIF, and PNG. You can create raster graphics using Paint on Windows, the Scratch sprite editor, or Preview on Mac. Though you may prefer a more robust image editor such as Photoshop or GIMP, which is a free alternative to Photoshop.
   • Vector: Unlike raster images, vector graphics are not made of pixels. They are made up of data points called vectors that are connected to create lines and shapes. They are the most widely used graphics on Scratch. Scratch supports scalable vector graphic (.svg) image formats. You can create vector graphics using Adobe Illustrator, or Inkscape which is a free alternative to Illustrator.
3.

   Start a new graphic in Scratch. To create a new background or sprite using the built-in graphics editor, hover the mouse cursor over the icon that resembles a photograph for backgrounds or the icon that resembles a cat for sprites. Then click the icon that resembles a paintbrush to open the built-in graphics editor.

   • To import an external graphic image, click the icon that resembles a trey with an arrow pointing up over it. Then select a JPEG/JPG, GIF, PNG, or SVG image and click Open.

   Use the shape tools. There are two shape tools in Scratch, the rectangle tool and the ellipse tool. The rectangle tool can be used to make squares and rectangle shapes. The ellipse tool can be used to make circles and ovals. Click the icon that resembles a square or a circle in the toolbar to the left of the drawing area. Then click and drag in the drawing area to create a rectangle or oval shape.

   • Hold the "Shift" key while you drag to create a perfect square or circle.

8. 
   8
   Use the reshape tool. The reshape tool is used to alter the shape of a vector object. To use the reshape tool, click the icon that resembles a mouse cursor clicking a dot. This displays all the vector points in your drawing. Click and drag the vector points to change the shape of an object.

   • To change a line from straight to curved, click a vector point with the reshape tool. Then click Curved above the drawing area. Click Pointed to make a curved line straight.
9.

   • To group multiple objects into one object, use the select tool to select all the objects you want to group together. Click Group above the drawing area to group them. Click Ungroup to separate objects that have been grouped together.
   • Unlike Bitmap graphics which are made of pixels, vector graphics are made of shapes that can be stacked on top of one another. To move an object behind or in front of another object, select it with the select tool. Then click Forward or Backward to move the object up or down one layer. Click Front or Back to move the object all the way to the top or bottom of your objects.
10.

    Select a color. To select a color, click an object with the select tool, or select a drawing tool in the toolbar. Then click the box that says Fill to select the color inside of an object. Click the box that says Outline to select a color for the line around the object.

    • To select a color, use the slider bar below "Color" to select the color hue. Use the slider bar below "Saturation" to select how much color is applied. Use the slider bar below "Darkness" to select how dark the color hue is.
    • To remove the color, click the white box with a red line through it in the lower-left corner of the color selection menu.

   Click the Code tab. It's the first tab at the top in the upper-left corner. This displays the code menu.
2. 
   2
   Click a sprite you want to apply code to. Sprites are listed below the play area to the left.
3. 
   3
   Drag an event block into the code area. In Scratch, coding is done in visual blocks. Event blocks are listed below "Events" in the list of blocks. These indicate an action that triggers a script. Examples include, "When [green flag icon] is clicked", "When [keyboard key] is pressed", or "When this sprite is clicked".

   • Some blocks have drop-down menus you can use to select an option or a white text box you can use to input your own value. For example to assign an action to a keyboard key, drag the block that says "When [space] is pressed" into the code area. Then use the drop-down menu in the block to select a keyboard key.
4. 
   4
   Attach an action block below the event block. Action blocks make something happen when the event is triggered. It can make objects in the play area move, trigger a sound effect, display text, or change the score. Attach an action block to the bottom of the event block so the notches line up. Use the following steps to create simple movement controls:

   • Select a sprite.
   • Add an event block that says "When [right arrow] is pressed" to the coding area.
   • Attach a block that says "point in direction (90)' below the event block.
   • Attach another block that says "move (10) steps".
   • Add a new event block that says "When [left arrow] is pressed" to the coding area.
   • Attach a block that says "point in direction (90)" below the event block.
   • Click the white circle that says (90) and drag the arrow so it points to the left. The block should now say "point in direction (-90)"
   • Attach another block that says "move (10) steps".
5.

   Click the green flag icon above the play area. This starts your program and allows you to test it. There are many combinations of blocks you can use. Try to experiment and watch lots of tutorials to learn how to get good at coding in scratch.

  How do I make it so that I don't need to press the green flag continuously in order to make the character move?

  

  Community Answer

  Instead of a "When Green Flag Clicked" block in front of the move commands, put a "When Key Pressed" block there.
