3D Disco Lights - SierraKen - 08-23-2022

I doubled up my Anemometer and turned them into disco lights! Plus I added a random setting to make them go at a random direction and speed if random mode is turned on. To turn it on press the Space Bar as it says in the title bar. If you press the Space Bar and it doesn't work, press it again a few more times, sometimes it's caught up in a loop I think. To turn random mode off press it again. Without random mode you can use the mouse wheel to change the speed and direction of the lights. Tell me what you think, thanks.

Cool stuff. I like the scroll-wheel control.

Thanks Smile

Great! It's even movable. What are the routines that create the movement?

I once designed a rocket with CorelDraw, but I couldn't get it moving. It's supposed to look like it's flying up.

For each of the lights, it does the following, where X and Y is the middle of the circle and w is the wheel of the mouse. r is the radius of the circle light. It's in a loop where t keeps changing making it go a full orbit. But t starts out outside of the loop with this: t = (_Pi / 2) * 100, which is just the radian of where the location of the orbit will be. I timed it by 100 to make it easier to understand. 
To get the mouse wheel, do this:   While _MouseInput: wheel = wheel + _MouseWheel: Wend     
Then I make w = wheel so I could also add the random mode. 

Code: (Select All)
    x = (Sin(t) * 20) * (_Pi * 2) + 400
    y = (Cos(t) * 10) * (_Pi / 2) + 200
    r = (Cos(t) * 180) / _Pi / 1.5 + 50
    t = t - (.25 + w / 10)
