Does anyone can tell me how i can make, that every Player sees the walking animation of a sprite and not just the sender of it?
When you send data you should always pass ID of client(Photon.MyActorNr) and also you should assign that same ID to objects that present player, other vise locating correct sprite(player) on each clients side would be impossible.
Set "Receivers" Others and maker sure that "TargetActors" are not defined(just ""), define TargetActors only when you want to target ONLY ONE client by his ID.
something like this, also have in mada that data is send as strings, so have in mind that you will need separate data with something in my case "|" and extract exact information you need like this: tokenat(Photon.EventData,0,"|"), index 0 would extract data before first "|" and index 1 would extract after first "|" etc.
