Special cloud behaviours

When the "Give certain cloud variables special behaviours depending on the name?" option is checked, an HTMLified project will react to changes to cloud variables.

WARNING: There is no prefix for these cloud variable names, so I may add a behaviour in the future that conflicts with an existing cloud variable in your project.

Cloud variable name	Description	Added
☁ eval	When you set ☁ eval to some JavaScript code, the project will run it, and the result will be stored in either ☁ eval output or ☁ eval error. If the code returns a Promise, the project will first wait for it to resolve.	2020-06-01
☁ eval output	The return value from the JavaScript code will be stored in ☁ eval output, if it exists.	2020-06-01
☁ eval error	If evaluating the JavaScript from ☁ eval resulted in an error, the error message will be stored in this cloud variable. If this cloud variable doesn't exist, nothing will happen.	2020-06-01
☁ open link	When you set ☁ open link to a URL, the project will try to open a new tab with that URL. Pop-up blockers might prevent this from happening, though.	2021-02-07
☁ redirect	When you set ☁ redirect to a URL, the project will be redirected to that URL (like clicking a link). However, this means your project can no longer run.	2021-02-07
☁ set clipboard	When you set ☁ set clipboard, it'll copy its value to the user's clipboard. However, browsers are pretty stringent on websites manipulating the clipboard, and if something fails, an error will be stored in ☁ eval error if the variable exists. Generally, copying in response to a click, or simply using a list, has a greater chance of succeeding. On Chrome, this only works on HTTPS or localhost sites.	2021-02-07
☁ pasted	Contains the last pasted text from the user.	2021-03-16
☁ set server ip	Setting ☁ set server ip will change the cloud server IP.	2021-02-07
☁ url	Contains the current URL of the web page.	2021-03-16
☁ local storage ...	If you're using a custom cloud server, variables whose names start with ☁ local storage will be saved in localStorage.	2020-06-01
☁ username	When set, it changes the value reported by the username block.	2021-03-16
Other	If you're using a cloud server, all other cloud variables will be saved in the cloud. Otherwise, the cloud variables will be saved in localStorage.	2020-06-01

There is also a global setCloud function that you can use. For example,

setCloud('high score', 10)

will set the cloud variable ☁ high score to 10.
