Disable mouse click on gameObject

I want to stop the player from being able to left click on the gameObject in c#

I have googled this and can’t seem to find the answer

There’s quite a few options on how you can do this @mullac51.
It depends on whether to want to allow the gameObject to be selectable again at some point.
If not you could simply delete the collider on the object.

Destroy(gameobject.collider);

or just disable it.

gameobject.collider.isTrigger = false;

You could create a tag for the object and test against that flag. If the object’s tag == ‘ignore’ than ignore.

if(gameobject.tag == "ignore"){
// Do nothing
}
else{
// Do mouse click code
}

You can also test against Layers.
