Online multiplayer bouncing ball game! this is an MQTT demo game thing I made one time. if two people open up this project they will connect to eachother. if you want to try it out but no one else is playing, just open the project in two seperate windows on your computer.data:image/png;base64,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Online multiplayer bouncing ball game! this is an MQTT demo game thing I made one time. if two people open up this project they will connect to eachother. if you want to try it out but no one else is playing, just open the project in two seperate windows on your computer.

Connect to a broker The options are not required but can be filled if needed 1. username (some brokers need this) 2. password (some brokers need this) 3. keepalive (default time is 60 seconds but some brokers need a shorter time) 4. connection callback (ringed set of scripts to be run when connection is made or remade) Note: The connection callback doesn''t have to be the 4th option - it just has to be the last (or only) option. ADVANCED: The brokers offered in the menu are accessed using default ports and basepaths (if needed). If accessing other brokers, the complete urls should be formed like this: siteURL:port/basepath e.g mqtt.eclipseprojects.io:443/mqtt It is possible to have more than one connection to the same broker, for instance, using two different user/pass accounts simultaneously. To do this, add a connection id at the end of the broker: e.g mqtt.eclipseprojects.io:443/mqtt|1

Publish a message to an MQTT broker The options are not required but can be filled if needed 1. qos (quality of service 0,1 or 2) 2. retain flag (boolean)

Subscribe to a topic on a broker Make sure you have already run an MQTT connect block before using this one You should add a script to be run inside he grey ring. It will be run each time a message is received If you click on the arrow on the grey ring twice, you can use #1 and #2 inside your script. #1 will contain the received payload #2 will contain the received topic name The options are not required but can be filled if needed There is only 1 option at present 1. Binary mode (boolean) If true, payload returned as plain binary byte string. Default condition (false) it is returned as UTF text string

This is a simple echo example. Topic can be used to filter the response.

The response topic should be a unique value for each call e.g. use timer The options are not required but can be filled if needed 1. Timeout value - default is 3 seconds 2.

Catch errors. Runs the first script. If it succeeds, nothing else happens. But if it has an error (something that would otherwise result in a red halo around the block), then the second script is run, with the text of the error message that would have been shown in the variable ERROR.

pt:tenta executar _ e, em caso de erro _ , executa _ ca:prova de forma segura _ i si _ _

Throw an error. Makes a red halo appear around the script that runs it, with the input text shown in a speech balloon next to the script, just like any Snap! error. This is useful to put in the second script of SAFELY TRY after some other instructions to undo the partial work of the first script.

pt:lança o erro _

Catch errors in a reporter. Evaluates its first input. If that expression successfully reports a value, this block reports that value. If the expression causes a Snap! error, then the final input slot is evaluated with the text of what would have been the error message in variable ERROR. SAFELY TRY then reports the value of that final expression. Sometimes you'll want to throw an error in the final expression. You can put an ERROR block inside a CALL block to do that.
