Hello ! I want to make programs for android. Unfortunately, I've been programming in Basic for 30 years, and it's hard for my brain to switch to object-oriented programming. I don't see and understand at all how they are built on each other, how things can be connected. A week ago, I tried the development system called B4A (https://www.b4x.com), which is in principle written in Basic, but in practice it could be anything due to the lack of simplicity.
I made a program in QB64 in a couple of hours, and then converted it to B4A. I suffered with it for almost 2 days before I rewrote it properly and it finally started.
I have attached APK file. This should be launched on Android and the program will be installed. Pretty much the same as the code here.
In the qb64 version, the mouse behaves like the touchscreen on the phone. The left mouse button simulates touching the touchscreen, and the move button simulates moving the mouse.
