That means that events are triggered throughout the whole page ([see the p5 docs for reference](https://p5js.org/reference/#/p5.Element/mousePressed)). If you would like to attach events only to canvas see the example below. As an example limiting click events to the canvas: ```javascript const setup = (p5, canvasParentRef) => { cnv = p5.createCanvas(width, height).parent(canvasParentRef) cnv.mousePressed((event) => { console.log("Clicked on the canvas. Event:", event) }) } ``` #### Using it in an SSR environment (Next.js or Gatsby) Importing this package for example in a Next.js or Gatsby app may give you this error: ``` ReferenceError: window is not defined ``` This is because importing `p5` requires `window` to be available, and it isn't when server side rendering. For Next.js we can fix this using [Next.js dynamic imports with No SSR](https://nextjs.org/docs/advanced-features/dynamic-import#with-no-ssr). ```javascript import dynamic from 'next/dynamic' // Will only import `react-p5` on client-side const Sketch = dynamic(() => import('react-p5').then((mod) => mod.default), { ssr: false, }) ``` For Gatsby we can use loadable-components. See [Gatsby docs: Load client-side dependent components with loadable-components](https://www.gatsbyjs.com/docs/using-client-side-only-packages/#workaround-4-load-client-side-dependent-components-with-loadable-components). ```javascript import Loadable from "@loadable/component" const Sketch = Loadable( () => import("react-p5") ); export default Sketch; ``` #### With p5.sound I frequently see this question even if the implimentation is super simple. The only needed thing is to import the p5.sound lib. I created a [special CodeSandbox demo](https://codesandbox.io/s/react-p5-forked-9ixi4?file=/src/index.js) if someone needs to see the implementation. #### With p5.sound + next.js (or other framework which has support for SSR) This question also is frequently asked and the only difference from the normal aprouch is that in SSR mode the react-p5 lib should not be loaded because p5 doesn't support SSR and there is no sense for it to be support. So, if you are using react-p5 plus next.js and you need p5.sound as well, then try to use dynamic imports as in the code below which will definitely help you. ```javascript import dynamic from 'next/dynamic' // Will only import `react-p5` on client-side const Sketch = dynamic(() => import("react-p5").then((mod) => { // importing sound lib only after react-p5 is loaded require('p5/lib/addons/p5.sound'); // returning react-p5 default export return mod.default }), { ssr: false }); ``` When using dynamic import, the type information for the methods extended by `p5.sound.d.ts` is not loaded. Therefore, we can use [Type-Only Imports](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export) to address this. ```typescript import dynamic from 'next/dynamic' // importing only type information from p5.sound addons. import type from "p5/lib/addons/p5.sound" // Will only import `react-p5` on client-side const Sketch = dynamic(() => import("react-p5").then((mod) => { // importing sound lib only after react-p5 is loaded. require('p5/lib/addons/p5.sound'); // returning react-p5 default export return mod.default }), { ssr: false }); ``` ## Props | Prop | Required | Type | Description | | -------------------------------------------------------------- | :------------------: | :--------: | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | className | :x: | String | ClassName for canvas parent ref | | style | :x: | Object | Styles for canvas parent ref | | [setup](https://p5js.org/reference/#/p5/setup) | :heavy_check_mark: | Function | The setup() function is called once when the program starts. | | [draw](https://p5js.org/reference/#/p5/draw) | :x: | Function | Called directly after setup(), the draw() function continuously executes the lines of code contained inside its block until the program is stopped or noLoop() is called. | | [windowResized](https://p5js.org/reference/#/p5/windowResized) | :x: | Function | The windowResized() function is called once every time the browser window is resized. | | [preload](https://p5js.org/reference/#/p5/preload) | :x: | Function | Called directly before setup(), the preload() function is used to handle asynchronous loading of external files in a blocking way. | | [mouseClicked](https://p5js.org/reference/#/p5/mouseClicked) | :x: | Function | The mouseClicked() function is called once after a mouse button has been pressed and then released. | | [mouseMoved](https://p5js.org/reference/#/p5/mouseMoved) | :x: | Function | The mouseMoved() function is called every time the mouse moves and a mouse button is not pressed. | | [doubleClicked](https://p5js.org/reference/#/p5/doubleClicked) | :x: | Function | The doubleClicked() function is executed every time a event listener has detected a dblclick event which is a part of the DOM L3 specification. | | [mousePressed](https://p5js.org/reference/#/p5/mousePressed) | :x: | Function | The mousePressed() function is called once after every time a mouse button is pressed. | | [mouseWheel](https://p5js.org/reference/#/p5/mouseWheel) | :x: | Function | The function mouseWheel() is executed every time a vertical mouse wheel event is detected either triggered by an actual mouse wheel or by a touchpad. | | [mouseDragged](https://p5js.org/reference/#/p5/mouseDragged) | :x: | Function | The mouseDragged() function is called once every time the mouse moves and a mouse button is pressed.

The keyCode for the key that was pressed is stored in the keyCode variable. | | [keyReleased](https://p5js.org/reference/#/p5/keyReleased) | :x: | Function | The keyReleased() function is called once every time a key is released. See key and keyCode for more information. | | [keyTyped](https://p5js.org/reference/#/p5/keyTyped) | :x: | Function | The keyTyped() function is called once every time a key is pressed, but action keys such as Backspace, Delete, Ctrl, Shift, and Alt are ignored. | | [touchStarted](https://p5js.org/reference/#/p5/touchStarted) | :x: | Function | The touchStarted() function is called once after every time a touch is registered. | | [touchMoved](https://p5js.org/reference/#/p5/touchMoved) | :x: | Function | The touchMoved() function is called every time a touch move is registered. | | [touchEnded](https://p5js.org/reference/#/p5/touchEnded) | :x: | Function | The touchEnded() function is called every time a touch ends. If no touchEnded() function is defined, the mouseReleased() function will be called instead if it is defined. | | [deviceMoved](https://p5js.org/reference/#/p5/deviceMoved) | :x: | Function | The deviceMoved() function is called when the device is moved by more than the threshold value along X, Y or Z axis. The default threshold is set to 0.5. The threshold value can be changed using setMoveThreshold() | | [deviceTurned](https://p5js.org/reference/#/p5/deviceTurned) | :x: | Function | The deviceTurned() function is called when the device rotates by more than 90 degrees continuously. | | [deviceShaken](https://p5js.org/reference/#/p5/deviceShaken) | :x: | Function | The deviceShaken() function is called when the device total acceleration changes of accelerationX and accelerationY values is more than the threshold value. The default threshold is set to 30. | ## Contributing 1. Fork it! 2. Create your feature branch: `git checkout -b my-new-feature` 3. Commit your changes: `git commit -am 'Add some feature'` 4.
