Set parent

I'd like to do something like this:

There's many soldiers on the map. They all moves randomly. All of them has its own crosshair (aim). If soldier sees another soldier in his crosshair he shoots.

There's my pseudo-code for this:

<font size="2">events:

• Start of level
• for every soldier

Action:

• create crosshair
• pin crosshair to soldier

event:

• crosshair collides with soldier

action:

• soldier fire

</font>

But wrong soldier is firing (not shooter-soldier but target-soldier is shooting).

I think it should be done like this:

<font size="2">events:

• Start of level
• for every soldier

Action:

• create crosshair
• pin crosshair to soldier
• for that crosshair set this soldier as parent

event:

• crosshair collides with soldier

action:

• parent soldier fire

</font>

Is there any action similar to parenting?

Im not quite sure what you are trying to explain, Please provide your capx, it gives us more of a chance to help you.

Are your soldiers separate sprites or just different instances of one?

You might have to assign a separate id to each soldier, in the sprites properties panel,

Try explain the game more,

Are you setting a cursor to the mouses position, and if the cursor collided with a soldier you want it to fire?

I think I understand what you want to do.

You want basically pick the soldier that possess the crosshair

You can do that quite simply like that :

create two instance variable for the crosshair object:

• soldierUID type number default 0
• firing type bolean default false

Global variable crossDist = 100  // Distance between soldier and crosshair
System: On start of layout
   -> destroy crosshair
   System: Foreach Soldier
      -> System: create crosshair on layer 0 at cos(soldier.angle)*crossDist,sin(sodlier.angle)*crossDist
      -> crosshair: pin to Soldier
      -> crosshair: set sodlierUID to Soldier.UID
System: Every tick
   -> crosshair: set firing to false
crosshair: is overlapping Soldier
   -> crosshair: set firing to true
crosshair: is firing
soldier: pick instance with UID crosshair.soldierUID
      -> Sodlier: spawn Bullet
      -> Bullet: set angle to Soldier.angle

Be sure also to read (again) how events work this could help you clean out your code.

Yann, thanks. It works perfectly.

Kyatric, I sure will.
