How protect a NPC from P-Switch?

[Seminesho]

How can I protect a dragon coin from being transformed into a brick block because of the effects of an activated P-Switch?

[RudeGuy]

That's impossible.

There is a Event that is already implemented in the Event Window called "P Switch - Start" and "P Switch - End". Those will trigger if you pressed the P Switch. You need a Layer that the Dragon Coin will disappear once you hit the P Switch and if the P Switch ends they must be appear. But that is a very buggy solution because doing so they will Duplicate the Dragon Coins and you gain more lifes than usual.

The other way is while the P Switch is active, make sure that the player is impossible to reach the Dragon Coin so he/she is not accidently breaking it and lose the chain of the Dragon Coin Points.

You can use a different switch (like the explosive switch) and use events to make it turn coins into bricks, but not the Yoshi coin.
