(Help) Make the player take and use a item

Hello, I'm doing my first project at Construct 2. I want the player get a boat in a certain part of the game to float on the magma. I created a sprite for the boat, wich has the solid behaviour. I want the boat to be an item and when the player is in colinsion with it, the boat disappears and the player gets a new sprite (player inside the boat). Also, after getting this item, the player couldn't die on the magma. How can I do it?

Thanks!

on collision player and boat:

set player variable state to 1

set player animation to "boat"

boat make invisible

if player variable state ==0:

+ player overlaping magma:

Destroy player (player die etc)

I did what you said, and the game froze XD I did it by another way and i got it... But thank you a lot!
