Armory node exemple help

Hello (Sorry my english is bad, i’m french), I try to understard controls.blend file in armory git Link

I do not understand how the car moves backward, the nodes to move forward and backward are identical.
Could you help me please ?

Check the vector in the nodes. One should be in a positive direction and the other in a negative direction.

Thanks to your reply but no, the two nodes are exactly the same.

There’s no way it’s the same. I haven’t looked at that example, but I bet you didn’t check vector out like @Monte_Drebenstedt said ? On your Vector Math nodes click “Vector”. You will see numbers for X,Y, and Z. There’s got to be one going in the negative direction.

Ok understood, i hadn’t seen this window. Thanks all !
