Hey I'm new to Unity and could use some help

I was trying to make the background look cooler by making it move with the camera, and I tried to make the middle one move at half speed to make it look better but then this happened

Any suggestions?

if u want the background to follow the camera a simpler way is to make the background a child of the camera.
Just drag the background to the camera in the editor

and if u want ur script to work just change ur code to

new Vector3(amountToMove.x*0.5f,amountToMove.y*0.5f,0)

thanks

So you know for the future, please note, you should use the Scripting forum for general scripting questions here.

Also, the forums provide the ability to post code using code-tags so we can easily refer to it by line-number, against error messages which contain line numbers etc.

Thanks.
