How do I manage families instances

hi guys, I have a enemy problem. If my player collides with 2 enemies in the same time ( enemies are in families), 2 lifes are subtracted, and two sound effects are played ( louder). But I would like only 1 life subracted... how can I do that ?

thanks

Should work (not tested)

You could use a timer. When colliding with enemy set the player to invincible - like old games where your player flashes for the next 2 seconds.

You can pick instance 0. That will limit the actions to one enemy.

thanks to all.... how shall i manage the pck instance 0 ? sorry iam not so good in C2

Actually that doesn't work, so a variation of the temporarily-invincible idea, this will disable subsequent collisions, only for the duration of the same collision time-frame.

Drag the green sprite over the red sprites. Just one will rotate. (If you keep trying they both will, but only because you aren't actually colliding at the same time, which is the correct behaviour).

thanks 4 Ur help
