I asked the same question years ago. Sry for that. The solution is here.

It works by overlapping but not by collusion. Why?

Hi basically I have the same question like maxrpg in this Topic.

Only that it doesn't work for me. And the difference maybe, that I have an Enemy-Family

So if there are 2 enemies overlapping each other the Bullet Sprite will subtract HP from both of the Enemies on collusion instead of only on. For example the one on top.

choose is a system expression. You have to type it.

The user tarek2 helped me out with this one. He wrote:

Use Overlap for that much better

-sprBullet : Overlaps sprEnemy
-sprEnemy: pick top instance
-Trigger once while True
Action :sprEnemy: destroy

The 3 conditions in the same Event [/code:38wux4to]

It worked perfectly. Still thank you both for replying

Ah great! I tried it how you explained and it works perfectly now! Thank you very much

Hi, I was trying out the "pick top/bottom" action but something went wrong. So I have 4 or 5 same sprites overlapping each other. And when the Bullet collides with a sprite, the sprite will be destroyed. However if the sprites overlap each other all 4 or 5 sprites get destroyed instead of one. Therefore I tryed to pick the top sprite and destroy only that, but something is not working.

-> sprEnemy: on collusion with sprBullet

--> sprEnemy: pick top instance -> sprEnemy: destroy

This is how my event looks like.

So it must be like this...

showing tenth of a sec

-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*10)%10), 1)

showing hundredth of a sec

-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*100)%100), 2)

showing thousandth of a sec (millisec)

-zeropad(int(time/60% 60), 1) & ":" & zeropad(int(time%60), 2)& ":" & zeropad(int((time*1000)%1000), 3)

...is this correct?

Here are two screenshots, I'm working on a shootemup asteroids clone.

You can play the game at it's current state here. BEAT THE HIGHSCORE

can I somehow save this post under favorites to find it later?

Hi,

if you have troubles with the black screen check if you saved your whole project (preferably in an new folder) before exporting. Under -> File -> Save As Project. Then open the new saved project-file and export it for scirra arcade. That worked for me at least.

cheers

Looks cool. Do you have a video of the game somewhere? Keep it up
