Gameobject Rotates on wrong axes | Official Unity Discord | Page 1

#

It actually rotates on both axes

#

restive silo Feb 11, 2022, 6:31 PM

#

you can just use

#

transform.LookAt(target);

#

so in your case it would be

#

Transform player =  GameObject.Find("Player").transform;
transform.LookAt(player);

#

You can read more about it here

#

https://docs.unity3d.com/ScriptReference/Transform.LookAt.html

#

Hope this helps

boreal matrix Feb 11, 2022, 8:04 PM

#

restive silo ```cs transform.LookAt(target); ```

With that code the Bot is now only rotating on the Y Axes

#

transform.rotation is now x=0 y=90 z=0

restive silo Feb 11, 2022, 8:11 PM

#

boreal matrix With that code the Bot is now only rotating on the Y Axes

Thats wierd

#

Maybe you have to set an extra direction

boreal matrix Feb 11, 2022, 8:11 PM

#

I tried some things with the New code

#

yeah thats what i tried

#

I works perfetct and always rotates to the player

#

just the axes is wrong haha

restive silo Feb 11, 2022, 8:13 PM

#

you could add an extra quaternion to it

#

to fix the axis problem

boreal matrix Feb 11, 2022, 8:13 PM

#

hows that

restive silo Feb 11, 2022, 8:13 PM

#

wait

#

Quaternion rot = transform.LookAt(player) + new Quaternion(x, y, z, 0)
transform.rotation = rot

#

this should work

#

but i am not sure

#

and then you add like 90° on the x axis or stuff

boreal matrix Feb 11, 2022, 8:15 PM

#

hmm

restive silo Feb 11, 2022, 8:17 PM

#

does it work

boreal matrix Feb 11, 2022, 8:17 PM

#

hold on

#

what do you mean with x,y,z

restive silo Feb 11, 2022, 8:21 PM

#

the offset

#

like +90° on x

#

if you dont wanna change for example the z axis change z to 0

boreal matrix Feb 11, 2022, 8:22 PM

#

so 0,270,0?

#

but it wont help the z axes to rotate

restive silo Feb 11, 2022, 8:24 PM

#

idk how it looks in your game i just know that the axis are messed up

#

and an offset could help

#

maybe send some screenshots

#

it would help

boreal matrix Feb 11, 2022, 8:24 PM

#

yeah yeah 1 sec

#

Default Bot Transform

#

Executed with lookat(Player)

#

3D View Executed

restive silo Feb 11, 2022, 8:33 PM

#

wait is it a 3d or 2d game

boreal matrix Feb 11, 2022, 8:34 PM

#

2d top down

restive silo Feb 11, 2022, 8:34 PM

#

why dont you say that

#

bruuh

boreal matrix Feb 11, 2022, 8:34 PM

#

its just the 3d view of the 2d game

#

lol

#

why?

restive silo Feb 11, 2022, 8:34 PM

#

i thought it was a 3d game

boreal matrix Feb 11, 2022, 8:34 PM

#

no😕

restive silo Feb 11, 2022, 8:36 PM

#

try

#

transform.LookAt(player, Vector3.back)

boreal matrix Feb 11, 2022, 8:36 PM

#

good idea

restive silo Feb 11, 2022, 8:37 PM

#

transform.LookAt(player, Vector3.forward)

#

or this

boreal matrix Feb 11, 2022, 8:37 PM

#

ohh

#

it does in fact now rotate the Z axes

#

but y aswell

#

I tried to do transform.rotation = transform.rotation + new Quaternion(0,-90,0);

#

but it wont work 😦

restive silo Feb 11, 2022, 9:05 PM

#

did you try both

#

forward and back

#

maybe the player is higher then bot

#

thats why he looks up

boreal matrix Feb 11, 2022, 9:07 PM

#

so, i tried some more things

#

i tried both forward and backward

#

now what i did was: transform.right = PlayerTransform.position - transform.position;

#

and it kinda works

#

KINDa

#

GOT IT

#

just need to modify something

restive silo Feb 11, 2022, 10:22 PM

#

thats great

#

gl on your project

boreal matrix Feb 11, 2022, 10:22 PM

#

thx a lot for help

#

i got one last question

restive silo Feb 11, 2022, 10:23 PM

#

boreal matrix i got one last question

sure

restive silo Feb 11, 2022, 10:23 PM

#

boreal matrix thx a lot for help

nah np

boreal matrix Feb 11, 2022, 10:23 PM

#

how do i set my for example: Z Rotation +90 degrees

restive silo Feb 11, 2022, 10:24 PM

#

so can you send me your code part

boreal matrix Feb 11, 2022, 10:24 PM

#

sure

#

give me 10 mins i gotta help my dad

restive silo Feb 11, 2022, 10:24 PM

#

take your time

boreal matrix Feb 11, 2022, 10:42 PM

#

transform.right = transform.position - PlayerTransform.position;

#

thats it

#

no more needed

#

now its just off by 90 degrees

#

is there any way to change the transform.roration.z by 90 degrees?

restive silo Feb 11, 2022, 10:43 PM

#

didnt know that you can set transform.right

boreal matrix Feb 11, 2022, 10:44 PM

#

same

restive silo Feb 11, 2022, 10:44 PM

#

transform.rotation.z += 90

boreal matrix Feb 11, 2022, 10:45 PM

#

i did exactly that but it telly my that transform.rotation isnt a changable variable

restive silo Feb 11, 2022, 10:45 PM

#

whats the error code

#

if not try:

boreal matrix Feb 11, 2022, 10:46 PM

#

Assets\Scripts\Bot Scripts\Bot_Behavior.cs(49,9): error CS1612: Cannot modify the return value of 'Transform.rotation' because it is not a variable

restive silo Feb 11, 2022, 10:46 PM

#

transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y, 90, 0);

#

and does it work?

boreal matrix Feb 11, 2022, 10:50 PM

#

it locks it to 180 somehow

#

even if i do transform.rotation = new Quaternion(transform.rotation.x, transform.rotation.y,transform.rotation.z + 90, 0);

restive silo Feb 11, 2022, 10:52 PM

#

then try it with euler and local

#

transform.localRotation = Quaternion.Euler(transform.localRotation.x, transform.localRotation.y, 90);

boreal matrix Feb 11, 2022, 10:53 PM

#

totaly forgot about local

restive silo Feb 11, 2022, 10:54 PM

#

yes same

boreal matrix Feb 11, 2022, 10:58 PM

#

when i do transform.localRotation = Quaternion.Euler(transform.localRotation.x, transform.localRotation.y, 90); it will lock it to 90 on z. but if i do transform.localRotation = Quaternion.Euler(transform.localRotation.x, transform.localRotation.y, transform.localRotation.z + 90f); it will move it by 1 degrees depending on which side i am

restive silo Feb 11, 2022, 10:59 PM

#

what do you wanna achieve

#

that is has an offset of 90 degree

#

transform.right = PlayerTransform.position - transform.position;

#

this is all your code?

boreal matrix Feb 11, 2022, 11:00 PM

#

The bot is now facing at me with his side if i would rotate him by 90 degrees i would line him up to face me in my eyes to his eyes

#

yk?

restive silo Feb 11, 2022, 11:02 PM

#

yes

boreal matrix Feb 11, 2022, 11:02 PM

#

#

90 turn and i would have it

restive silo Feb 11, 2022, 11:02 PM

#

can you send me all your look code

boreal matrix Feb 11, 2022, 11:03 PM

#

restive silo ```cs transform.right = PlayerTransform.position - transform.position; ```

thats all of the code i need to rotate him in my dir

restive silo Feb 11, 2022, 11:03 PM

#

but you have to set the transfrom.right somewhere

#

or am i wrong

boreal matrix Feb 11, 2022, 11:04 PM

#

wait how do i tell dc its a cs script again

restive silo Feb 11, 2022, 11:07 PM

#

three of them

#

then cs

boreal matrix Feb 11, 2022, 11:07 PM

#

k

restive silo Feb 11, 2022, 11:07 PM

#

gotta remove all variable declarations at the start to put it in here

wäre es schlimm wenn du einen rigidbody auf dem spieler hinzufügen müsstest

boreal matrix Feb 11, 2022, 11:15 PM

#

überhaupt nicht

#

ist sogar eigentlich schon

restive silo Feb 11, 2022, 11:15 PM

es würde vieles erleichtern und außer führt das auch zu smootheren ergebnissen

restive silo Feb 11, 2022, 11:15 PM

boreal matrix ist sogar eigentlich schon

ah perfekt

meinst du ich sollte mein movement auf meinen rb überschreiben?

#

Ich kann nicht PlayerTransform.position - rb.position nehmen

#

eins ist ein vector 3 anderer 2

restive silo Feb 11, 2022, 11:32 PM

#

dann mach

okay

genau so hab ichs

#

aaber

#

ich krieg nen error

da soll ne null reference exeption sein

#

komme nicht drauf

#

ah ne

#

habs gefixt

restive silo Feb 11, 2022, 11:37 PM

#

okay geht es jetzt

boreal matrix Feb 11, 2022, 11:38 PM

ja musste nur bisschen was ändern

#

aber vielen dank für deine Zeit und Hilfe!

#

Muss jetzt nur bisschen schauen das ich alles verstehe was da neu ist und dann kann ich weiter machen 🙂
