Why is that when i try to assign a variable i always get an error saying that it is read-only?

Question

Read-Only! Please explain.

Answer 1

int i = 5; will not give an error.
Can you give an example?

Answer 2

Use get component to grab the collider as an object.

mainPlayer.GetComponent(collider type);

Though you're likely looking to add the component, so you can use:
mainPlayer.AddComponent(playerCollider);
This will add the playerCollider component to the GuiTexture.

Answer 3

Thank you very much! It solved my problem.

Answer 4

I'm not sure if you've ever worked with unity but if you do here is an example.....

GuiTexture mainPlayer;
Collider playerCollider;

mainPlayer.collider = playerCollider;
I cant assign the collider to it and it says it is read only.

Please let me know!
