I am really confused by the file. I see one box going up out of sight and the other just lands on the plane?
the collision sensor doesnt do anything…
I played with it…and discovered something, a weird thing…
So, when I unparented them, the child fell down to where it was originally made. So I moved it back up and pulled it farther away to see it better.
Then did a ctrl a. Then parented it back again. Then I clicked show physics visulization in the game menu.
Then I deleted the bounds for the child, and pushed compound for the parent, so it knows it has a child.
Then p. Now there are 3 boxes, two do what they are supposed to, I think, I didnt try the keys, and the 3rd one, is where the child was before pressing play.
I dont get it and am going to bed, lol. But you can download the file and dont change the view, just p and watch it. Might help.
Anyone passing through is the above normal for parented objects? In the picture below, on the left at the top is the parent, and on the right at the top is the parent and child, and at the bottom is a ghost child.
Later: after playing with the file some more (always learning), I unchecked use visuals, and changed the mode to solid, and now the parent, and the ghost are all that show. The one inside the parents box doesnt show.
So is it still there? LOLOLOLOL. that was fun!
