beginner questions - please help

i started with top down template.

i copied character, so now i have 2 chars, but by mouse click moves only the second one, not both of them, why?

BEcause only on has player controller input, and only one is possesed by player,

Do you mean to controll input blueprint?

How can i see which blueprint attached to which game object?

You can use the node GetPlayerCharacter together with PrintString for example to see which one is controlled.

Generally if you want to use multiple pawns at once, you’ll have to implement that yourself. For example giving your player controller of all pawns a player does currently control. And on whatever input (e.g. mouseclick) you perform the same action on each of the pawns.
