Hello every body, I am a newbie trying to make a ski game
Started this project a few years back during the quarantine (had time to spend lol)
I am now trying to make my input with the input system and use a controller but I am having issues
The AddRelativeTorque is not working as I understand it should…
I’ll share my code and a video to illustrate my problem below
I have floats speedFlip and speedTurn that should impact the speed my player turns on the ground and spins in the air
For this I add a relative torque to my player Vector.up which is multiplied by the input value of my joystick and the 2 float described above, but even though this value manages to be modified as I would like, the angular velocity of my player is the same no matter what the joystick input is
On the screen you can see the values of speedFlip and speedTurn (which should impact the value of the torque added to the player) and the angular velocity of the player
