the picture shows the front right side of a small submarine that I have modelled long time ago.
The task what I want to do now is to get the correct movement when pressing a key:
A = move forward
S = move up
X = move down
Y = move backwards
So the first thing I did was to set the “A” key for forward movement. After some googling I found a solution thats work, so that the frame of the propeller rotates 90° in X-axis and the propeller starts rotating. After release the “A” key the frame keeps its position and the propeller stops rotating.
So now I come to the main issue. When you now press the "S"key the submarine shall dive in positive Z-axis direction. Means the frame of the propeller needs to get in a horizontal postion. When you have pressed “A” then it needs to rotate back. When not, it needs to stay in the horizontal position. So how can I do this? Is it possible to do it without python script?
