First of all, let's call the 'green particle' a rain drop. I want the rain drop to spawn in randomly and always from the top of the screen. I want it to fall all the way to the bottom and then delete itself. Furthermore, I want there to be multiple raindrops, but not too many as the player needs to avoid them. Finally, as the game progresses I want the amount of rain drops to increase, therefore it's harder.

so i don't have the time to help with the whole thing but one thing i can let you know right away is you can't actually use particles for this. particles are incapable of collision checks. you need proper objects.

#

because you want them to interact with teh player

  1. You will want to create a raindrop object with the raindrop sprite assigned to it, in this object you will give it a collision check for both the floor and the player. You will also give the raindrop some code in its step event such as y += 1
#
  1. you will need to create a second object which will manage spawning in all the raindrops. First you will need to set up a timer in the object, when this timer reaches zero a raindrop will be spawned and the timer will be reset, you could do this using a variable or using an alarm, i will use a variable as an example
#

In the create event of this raindrop spawner object give it 2 variables, one called raindrop_cooldown and set it to something like 60, and a second variable called raindrop_timer and set it to = raindrop_cooldown

#
  1. finally you will need to have some code in the step event of the raindrop spawner
#

In the step event you will want something like ```if (raindrop_timer-- <= 0) {
raindrop_timer = raindrop_cooldown;
raindrop_cooldown -= 0.25;
var _x = random_range("left most x coord raindrops can spawn", "rightmost x coord");
var _y = "the y coord you want the raindrops to spawn at";

instance_create_layer(_x, _y, "The layer they are spawned on", o_raindrop);

}```
