I need help with a scoring system

I'm trying to make enemies drop power-ups every 10 points without having to use more actions and events.

Obviously I don't know exactly how your game works but you can do something similar to :

Global variable for Score (which you probably already have)

Global variable for DropCount, which starts at 0.

As you add 1 to Score, add 1 to DropCount.

When DropCount hits 10, drop an item, set DropCount to 0.

Depending on how your game works, the drop event could be a pick of the nearest enemy, or one that was just destroyed etc.

How can code the nearest enemy instead of on destroyed?

If you want the nearest enemy to player, create an event using the enemy, select Pick nearest/furthest from the list and then set the x,y co-ordinates to player.x,player.y

This should be posted in the "How do I?" section of the forums.

Thanks plinkie

Okay so i got another question. I have an weapon power up pickup spawning from the enemy correctly now. My player shoots a bullet from from image 1 and that bullet is a sprite. Now i have made 2 more bullets as sprites. I have an enemy dropping the power up for the bullet. How would i put the new bullet sprite to spawn after getting the powerup?

Put the new bullet sprite as one of the animation frame for the bullet. Create a variable called powerup. after the player gets the powerup, set the powerup variable to 1. If powerup=1 then set frame to 1(the new bullet sprite that spawn after getting the powerup)

I did all that but the new bullet sprite wont continue shooting. It shoots one of the new bullets then it returns to the original bullet.
