Hi @Tatyana_Lozinsky
the white line is the action flow ,
You correctly connected the begin event to: creating an instance and setting the reference variable .
You may need also to enable the input for your player 0
And when you hit 1,
you need another variable int that start with 0 “counter”.
when you hit 1, you need to check
if the Counter is < of the lengt of the array : add 1 set the texture parameter value using the counter in the get.
IF is not, you can set back the counter to 0, to cycle all the textures.
and again , set the texture parameter.
Beware in your screen you didnt connected the action line “white” to the set texture parameter !
So for now the only action key 1 does is setting the newvar to 0.
add a white line of action , from the set var 0 to set texture parameter
