Raycasting Stopped Working all of a sudden

Hello, i am using a script to select units with raycasting. W$$anonymous$$le the script used to work just fine. All of a sudden it stopped $$anonymous$$tting both the terrain and the objects. I have many objects with colliders on them. I haven't changed the lenght of the ray, nor the camera position. I am checking in the code whether the name of the object that's $$anonymous$$t is Archer or not. But even if i remove that condition. The Position of the object $$anonymous$$t is always 0,0,0. There's not$$anonymous$$ng in front of the camera. The y value of my colliders are too $$anonymous$$gh.20 of x value is equal to my 17.500 of y value on colliders only.. Don't know what causes them to shrink so much. Edit: I figured it only works if the collider is long enough towards the camera, but then i have to make it gigantic. I tried using mathf.Infinity Please help me. Here is the code that uses raycasting.
