FPS Cockpit Y-Axis Orientation Problem

by wurghi on Dec 3rd, 2014 06:55 AM

hi guys, i'm currently working on a cockpit based game in unity3D.
After some time of playing, especially with low FPS(i think) my dive drifts away a little. It doesnt keep on drifting, thats not the problem. The problem is after a little bit of playtime, the pan-orientation(y-axis only afaik) of the player has to be adjusted. So you cant just sit on your couch facing your TV and the front of your cockpit is always where your TV is. Sometimes after some playing time its like 90° next to you or even behind you...- Anyone else has this problem?

I'm currently thinking about adjusting the PAN rotation(y-axis) with the compass input from unity or something... Anyone has an idea how to solve this bug or did i miss something? Played the tuscany demo and there's the same problem

should be able to make the virtual north being in the same direction as the real north..


Grüße, Olli

You can easily see the problem like this: download tuscany demo, start while facing your device in one direction like your TV, stand still ingame, tip screen until max graphics is enabled, rotate to the house where FPS drops, shake device a little, rotate back to he sign, your device should face another direction then it had when you started the APP :/

fixed it, but was a pain in the behind.

i'm using the compass to "corrrect" the y rotation. Code is seperated in multiple different scripts so here's a short explanation how i did it.

first of all record the delta-rotation of the dive-rotation-gameobject every frame to a seperate var.

then make a new gameobject, attach the cameras to the new GO and rotate it with that deltarotation

the point of that is that we rotate a seperate GO with the gyroscope and still be able to change its Y-rotation. the standard Dive-rotation-Gameobject is linked to the gyrosensor alone and cant be corrected.

now attach a new script to the new gameobject that makes it rotate towards the direction of the compass smoothly. That way we can change rotation with the gyroscope very directly but overtime the compass corrects the y-rotation.
script should contain sth like this:



hope you get it, sry im in a hurry, maybe i can post code later
best regards

I'd also very much like to give this a go if you have a chance to post the code!

[color=#000000][size=3][font=Helvetica Neue, helvetica, Arial, sans-serif]What exactly is meant by Y-axis orientation? I was searching to find some solutions since my lg tv screen share not working, but came across talk about this orientation. I really am curious now as to what it means.[/font][/size][/color]
