[Solved] Player controller rotation

malak · Nov 15, 2018

hey everybody ,

i have a little trouble in a script i can't solve

i want my character move where i look but with this script it rotate my character where i look but for some raison i dont want rotate my character (i'm working on VR and rotation broke the gameplay).

i just need a simple script who move where i look but dont rotate .
here is the script i use who rotate my character :

Code (CSharp):

i hope you understand what i mean and sorry for my bad english i'm french

Don't just copy scrip which you don't understand. At least try to study it, or debug.
Start from something simple. Look up tutorials.

malak · Nov 15, 2018

yeah that's why i'm here and ask for help because i don't find a way to solve my problem , i can solve it by puting this script on cube and make my character follow him
but i want do something simple and clearely .

if you want explain me why it rotate and not just take the direction your welcome my friend

Antypodish · Nov 15, 2018

There is near 500 lines of script with comments.
Sorry but I am not going to analyse how this works.
Will be meaningless to guide, if is not your script.

If you really want to use it, I suggest strip id down, reverse engineer, use Debug.Log (), Step Debug, or any of these combinations.

Other option, is to ask / wait for someone else to popup to assist you.

And of course, best option for you, is to build a prototype, from working cube as you have tat part done, as you saying.
All best.

malak · Nov 15, 2018

I find a way for people who looking for solution

add empty object in your character and set the script rotate the empty object and make your character move in the rotation of your empty gameObject

That's it , enjoy
