I'm still learning this engine, myself, but this may be your answer:
makeinv {int} {bi}
~Determines whether or not the character is briefly invincible after being respawned. Otherwise, traps and enemies may be able to attack the player as they reappear- not nice.
~(int) is how many seconds the player will be invincible for.
~(bi) is flag which sets blinking
0 = Blinking (default)
1 = No blinking
~{int} also controls how long the parrow and parrow2 are visible.
~You can also use makeinv in item type entities. This will create an item that gives the player {int} seconds of invincibility , much like a star in Mario.
If not used blinking is on by default.
