star fall mechanics

1. make a java model (entity model) for your shooting star.
2. make a texture for the shooting star
3. create new living entity in mcreator
4. disable spawn eggs
5. if you want it to glow, make a new model layer with the same texture and enable glow
6. make it drop an item (optional) like a shooting star item or block that the player can obtain when it hits the ground.
7. make it immune to everything
8. make it have a sound (if you want like a shimmering sound player randomly)
9. remove all the ai blocks and keep only look around
10. disable entity spawning
11. save mod element
12. create new procedure
13. name it something like shootingstarfall
14. make it a global trigger and set it to player tick update
15. put an if block
16. in the condition put, is night in the world block
17. in the if block, put another if block
18. for the condition put a number compare block in the logic section
19. in the first slot put the block random integer between min max included from the math section
20. in the first number input put one, in the second number input put something like three hundred which makes how rare it is
21. in the second slot of the number compare put one
22. now the condition is if a random number between 1 and 300 is equal to  1 do...
23. in the result part of the if block, put a spawn entity at x y z block
24. put in your shooting star entity
25. in the x position make it y + 35 using the math block, this makes the star spawn 35 blocks above the player
26. in the x and/or z do the same or put a number like 20 to make it spawn 20 blocks away from the player
27. then test it in game!

if you want it to spawn at different distances from the player use the random integer block with a min of like 20 and a max like 30 or even the same with the z position if you want it from more directions
