How to allow a ray-cast through a player?
I am creating an item pick up script, and the main purpose for it is to check the tag and info on another script attached to a game object or the item. What is happening to the ray though is it is passing through the player, my question is how do i allow a raycast through the player object?
Thank you ahead of time.

Do what Johat suggested, or use RaycastAll and iterate through the hit colliders until you've found the one you need.
The simplest way to achieve this would probably be through a LayerMask. See the Physics.Raycast reference here.
If you put the player on a different layer to the GameObjects you want to check against, then you can mask that out to ignore it.
I would have a field in your script of type LayerMask since this will give you a nice drop-down in the inspector -- you can choose multiple layers to ignore easily if you like.
Something like:
public LayerMask IgnoreLayers;
Then your raycast could be something like this (check the reference for the version of raycast you want to call):
// Bitwise not -- ~ -- flips all the bits of the integer in this case, to allow every layer EXCEPT those you selected in the LayerMask
Physics.Raycast(someOrigin, someDirection, someMaxDistance, ~IgnoreLayers.value);
