Sorry it's a mess, but take a look at the DeerAi eventsheet, and also the part after the comment 'Spear collide behaviours'.
Basically, I just added in the last part to DeerAi, which is what to do if the Deer family has the state "dead".
Before that, everything worked properly, with the individual instances of the Deer family moving indepedently.
However, now I want to have that, when the spear collides with either DmgHead or DmgBody (both are part of the Deer family), then the nearest entire 'Deer' instance would be set to "dead". With the state of "dead", then the Deer instance would stop moving and stop animating (for now because I don't have the 'death' animation ready).
I don't know why this isn't working. In the main event sheet, it works with setting the collision boxes (DmgHead and DmgBody) every frame to follow the image points of each individual Deer instance.
I think for reason, the Spear is setting the variable ('state') of all instances of the Deer family, but I have no idea why. I tried using Pick Nearest to the spear on collision, but that doesn't work either.
Edit: I'm starting to think I confused a Container with Families <img src="smileys/smiley5.gif" border="0" align="middle" />
I wanted the Collisionboxes + Image Box of my Deer to be together. I probably should have used containers over grouping together in a family.
