How I could draw lines with arrows at the ends

You can start learning all you need to learn to do it, then do it, after long days of trying things, testing and failing, all in your spare time, leaving other things you like to do for this.
Then after all that time and intellect invested, just give it out for free so everyone can make money with it except you.
Sounds awesome right?

Yes, you are right and I understood that.
Anyway, I started another project, but I don't see how I could draw lines with arrows at the ends. There is no LineStartCap, LineEndCap, etc. like in C#.
Here is my project:

You could start by initializing global variables to 0 .

Empty sockets are an error.

Also, read the chapter on procedures in

App Inventor 2 Book: Create Your Own Android Apps

particularly the part about procedure parameters.

Maybe this can be useful to you:

How do I get the app to draw this?

This will draw an arrow on a canvas 300x300 [image] [image]

Here's just the arrows part:

If we wanted arrows at both ends of the line, both pointing away <---> ?

@TIMAI2

both pointing away <---> ?

Do one arrow pointing in the opposite point order to the first order, so one overlaps the other.
