Yeah! I guess that's true. I never really put a lot of thought into working collaboratively before, it's much more work than I originally imagined, even if you each had separate save files they wouldn't merge, I guess separate event sheets that are included in a master sheet would be the way to go.

On line 82 is where I have the actual dive action, I'm using custom movement but the bullet with "set angle of motion" should work just fine.

On lines 83 and 84 I set an instance variable to store the angle of flight I want the flyer to go after the dive is over, the "FlyAway" Instance variable is then used on line 86.

Note: You will most likely need to mirror your sprite.

General Tip: I noticed that lines 79&80 can be combined by right clicking on the condition box and changing it to an "Or Block", This Event Sheet is from an open project of mine, it's not yet optimized.

Can't figure out how to post a pic, I will try my best to keep this simple.

Set up a condition that tell the flyer to attack player, then us an action "set the angle of motion" (bullet behavior) towards position of "Player.X", "Player.Y"

You will then need a condition to disengage the player, at that point you could simply angle the flying object to something like 40degrees until it reaches a certain height, then set it to 0degrees.

For the 70, 20, 10 chance, you could do the following: create a local variable (for this example I'll call it ItemClassSelector).

In the event you currently have, set ItemClassSelector to int(random(1,11))

Then use 3 sub event, 1: if ItemClassSelector <=7 then pick from common ; if <=9 & >7 pick from rare ; if =10 pick legendary.

For the animation selection use more sub events. If common set animation to "common", If rare set animation to "rare", If legendary set animation to "legendary".

Nothing will stay unlocked until you start saving, here is a tutorial:

I assure you saving will seem really wired and complicated at first but it is really simple once you get a feel for it.

The data structure you will want to use to save variables is a dictionary.

I personally use this method, you will have to edit the string, but it's good practice and the tutorial is straight forward.

My guess: In the bullet behavior properties menu, disable "set angle"
