Look at the Translate or Add Force action and choose Z axis in Self Space to move it forward.
Get button will return an Input result from the Input Manager for the named input you typed in. You could multiply that result or use it as a bool to enter another state that applies the movement.
Thanks you for you help.
But unfortunatly, I'm still stuck.
1/ I added a
GET BUTTON and stored the result as a "
BOOL" variable
2/ Following your advice i tryed a "
TRANSLATE" , but i cannot connect it to a "
BOOL" variable.
In fact i have no idea how to connect the "
GET BUTTON" , to another action. (I assume, it aks Vector3 action)
