Video descriptions: Box Collider from my player does not want to react to the cube (object), although everything seems to be normal in the script. But when I put the Item tag on the player, the Box Collider immediately sees that there is something in its zone with the Item tag and does not react to the cube.
Please write the correct squeak or snare on it, so that in the Box Collider zone (from the player) everything with the Item tag reacts, or make it so that the item is picked up at a certain distance. And only when the bear is pointed at him! Don't lift your back.
About 11 am I sit and ate to make such a script. It's 21:00 now.
Doc.
