naval battle

hey working on my shipbattle system :)

i got some problems,

basicly is want to know if my ship should shoot left or right or both

i had something going but it doesnt work for multiple ships

i was thinking of using pickedcount and is clockwise or not, so when there

nr of ships is clockwise, enable right shooting

nr of ships is counterclock enable left shooting

but it doesnt work

by the way, should pickedcount not give a -1 or something if nothing is picked, its not very usefull like this

i prepared a cap for testing, so if somebody wants to help, cause im hitting a wall here <img src="smileys/smiley5.gif" border="0" align="middle">

is it hard to do maybe? any idea's?

don't have a solution for you, but I think I'm having the same sort of problem, and i think it's due to me not understanding picking instances very well

anyway, here's what i would like to do:

1) generate a random amount of enemies on the screen in random positions (i've been able to do that much!)

2) i want to be able to recognize what side of the player sprite the enemies are (this is where i'm getting tripped up);

   if i manually create a single instance of the enemy sprite and place it on the view area myself, it seems to work

   I was thinking if i go through an 'every instance of enemy sprite' loop and check if it's clockwise or counterclockwise from the player sprite it would work but nope!

anyway, here's the capx -

rojohound very nice, thank you!

thanks for quickfix, but I do have to ask... HUH!

i can see it working, but logically i don't get it, why wouldn't my way of looping through each instance of sprite not work,

or in other words why do you need to create a new instance variable just to assign it a UID that's created automatically anyway

Yeah... I agree I left out my my logic for the fix, which makes it not very helpful. So here's my trail of thought:

Events 5-7 in your original capx only filtered the "Sprite" object. "Sprite2" is unfiltered and only the first instance of "Sprite2" is used in the expressions. "Text" is also not filtered. So it runs like this:

if "Sprite" is CW from the first "Sprite2" then set all the "Text" objects' text to 'Left'.
if "Sprite" is CCW from the first "Sprite2" then set all the "Text" objects' text to 'Right'.

Text|Pick nearest to (Sprite2.X, Sprite2.Y)

System|pick Text instance Sprite2.IID
