I continue my luaRT module learning studies. Of course, the best way to learn is to practice. So I made a simple app to learn. Move the picture-shaped plane according to the arrow directions, but do not hit the barriers.

Great work cos00kun ! 👍
Still on holidays but I will try it as soon as I get back home

cos00kun

[Login to see the link] enjoy your holiday. I will write more apps 😃

Can you tell us about how you feel when coding this sample with LuaRT ?

cos00kun

I enjoy using LuaRT. Because it is very easy and convenient to use. I always love simplicity and LuaRT is a simple library for ease of use

cos00kun

but you deserve an appreciation for this because you are the one who gave it to us . 👍

cos00kun

The program closes when clicking on status bar
And if some modules are not completely closed and cannot be reloaded, I am sure it will be much more perfect. I'm looking forward to the new version🙏

cos00kun

Hi ...
For example, we put 20 checkboxes in our window. Is there an event in LuART that will react to us when we check someone?

Samir

You can use the same event function for all the checkbox.

if you need to know which one was checked, you can use the self.text property from the event function

cos00kun

Samir self.text
👍👍👍👍

Back to work today !
I just tried your example and I am just suprised by the result ! Thank you !

Samir Back to work today !

I'm glad to hear that. I am developing more now. now 8 balls will come out randomly at different speeds and bounce off the frames. I will post it shortly. In the next days, I will place a plane in the frame. We will control the plane and we will try not to hit the balls.

cos00kun

After that, I will make them act in accordance with the laws of physics. Luckily I'm good at physics and math 🙂

like I just mentioned. many balls are moving now. speeds and angles are completely different and determined ramdom. In the next stage, my goal will be to add a plane to the frame and control it. if the balls hit the plane we will get a warning. If we manage to escape from the balls for 1 minute, we will win the game. that's my goal. I think I'll be able to do it in a week.

cos00kun

There are some image pollution in the pictures in the game. I couldn't find the reason for this 🤔

Samir

There are some graphical glitches when the balls cross, because the ui module is not meant for this kind of demos, but more for classical GUI applications.

I have found a workaround, to force widgets to redraw once their position changed.
It will be available in next LuaRT version.
