I can't make an rpg bundle

I need help with that

you mean like 3rd person?
You need four keyboard triggers: up, down, left, right on the arrow keys. Connect the right keyboard behavior to a number of your choice, and the left keyboard to a negative version of the same number. Then connect them to velocity in the x axis.
(e.g. right - 5 - velocity, left- -5 - velocity)
do the same with up and down, with the y axis. (e.g. down- 5 - velocity, up - -5 - velocity) Then, with the UP output of the keyboard behaviors, connect a number 0 for each of them, that connects to the axis that they enter.

yes thank you
