How to edit source code with custom block.

[daviddanielng]

Hi everyone.
I downloaded a custom block from arabware, the block enabled replacing of parts of source code with my choice of code . I have looked at the block and I found out it is something different from how I know blocks are created.
It is something like this 👇👇👇

/*-JX4UA2y_f1OckjjvxWI.bQwRei-sLEsBmds7ArsRfi0xSFEP3Php97kjdMCs5ed>["public` class %2$s extends Activity {"]
>0
>0
>0
>find-replace
public class %2$s extends Activity implements %1$s {
BpWI8U4flOpx8Ke66QTlZYBA_NEusQ7BN-D0wvZs7ArsRfi0.EP3Php97kjdMCs*/
/*-JX4UA2y_f1OckjjvxWI.bQwRei-sLEsBmds7ArsRfi0xSFEP3Php97kjdMCs5ed
>["public class %2$s extends AppCompatActivity {"]
>0
>0
>0
>find-replace
public class %2$s extends AppCompatActivity implements %1$s {
BpWI8U4flOpx8Ke66QTlZYBA_NEusQ7BN-D0wvZs7ArsRfi0.EP3Php97kjdMCs*/

Can anyone tell me how to do this. I have search the internet but did not find any information.

That's just a Java Command Block. It and also the XML Command Block are available in Sketchware Pro v6.3.0 and newer. You can find them in the More Blocks palette like here:

after enabling this Mod Setting: (screenshot from v6.4.0, differently labeled in v6.3.0)

And also, if you need a tutorial on them, the #tips-n-tricks channel in the official Discord server has some. Invite link to the server is available in this repo's README.
