Every result is related to recording and replaying sound. But i want to record and replay the sequen🌏of button presses

[Kevinkun]

@S_Navaneeth_Krishna1

button presses

When button pressed, what will happen?

[S_Navaneeth_Krishna1]

A command goes to a robot making the robot do things

[Kevinkun]

So the app is like the piano app, just change ' play some note ' to ' send some command '.

Extension For Any Event

This extension allows you to intercept all the event calls in the screen. See here. [component_method] You have to call this block to initialize the extension. [procedures_defnoreturn] Once you have initialized it, you can create a procedure block like the above where you will receive the updates when an event is raised. For this to work, necessarily you dont have to drag any event. Example [image] Download:xyz.kumaraswamy.ai2tools.aix (10.2 KB)

Use this to intercept Button clicks or Any other event using this extension.

Your RECORD button is hilarious.

It is The Box That Shuts Itself Off.

You can buy one of those.

Here is an example of saving a timed recording.

The recording will disappear when you leave the app, because it has a list of button components.

so it records and replays in the correct time duration the btn is pressed.example if button one is pressed for 5 sec will the recording replay the btn press for 5 seconds

@S_Navaneeth_Krishna1

if button one is pressed for 5 sec will the recording replay the btn press for 5 seconds

This example uses Click events only.

What you want is TouchDown and TouchUp events, which would require an extra attribute in the timing event dictionaries. Study the MIDI data stream for one example of such a recording technique.

P.S. AI2 does not natively support multi-touch (multiple fingers on the screen simultaneously.)
