Create interactive gaming apps with the canvas component.
The canvas component is a touch-sensitive panel that enables the movement of items.
You can use this component to create a variety of games and experiences that involve different methods of touching a screen.
To add a canvas to your app, drag and drop the canvas component into the app builder.
When you click on the Canvas in your component tree, Canvas tab will appear. Click on this tab to customize your canvas
The three elements of a Canvas are the Stage, the Sprites, and the Canvas Label.
The Stage is the background of your Canvas. You can set a background color or background picture, a border color, and the stage's Height and Width. You can click and drag your Sprites on the stage in the Canvas tab.
You can set Gravity of the Stage along the X and Y axis. The Sprites on the stage can be toggled to ignore gravity or not. If a Sprite is affected by gravity, it will be pulled in the direction of the gravity.
Your Canvas Stage will automatically scale up in order to match the size of the device screen. If the aspect ratio of the Stage does not match the aspect ratio of the device, you can use Stage Scaling Mode to resize the background to fill the device screen.
Scale: The aspect ratio of the background will be maintained, and the background will be scaled up. May result in some of the background being cropped.
Stretch: The background image will be stretch in order to fill the screen. May result in the background image being distorted.
Select how you want your background image to be centered when it is scaled to match the device screen.
Can be set to center, center horizontally only, center vertically only, or none.
You can enable Touch Drawing on your Screen. You can set the Drawing Color to choose the color you draw in. You can set the Drawing Width to choose the thickness of the line you draw on the stage.
You can add multiple stages to a Canvas component, in the same way you can add multiple Screens to an app project. when you have selected your Canvas tab, click on the + next to your Stage name to add another Stage to the Canvas.
Each Stage has its own Sprites, background color, gravity, etc.
