"Kills one hero as other one revives" system?

[Marshmalo]

Ok I'm having a major problem with this and I've tried lots of things. Im trying to create a hero system which only allows you to have one hero at a time but allows you to rechoose them at any point through the game.

Example: if player revives one hero from altar then his current one needs to die to make room for the one he's just brought but I cant remove it from the game as it needs to be stored in the hero altar for later resurection. Ive tried killing every unit of type when player revives their hero but this kills the reviving/summoning hero as soon as it re-enters game.

All help appreciated with this

(ps: I don't have jass or know much about variables)

Simple, you store the active hero in a unit variable (a variable is like a maths variable).
You then when they get another hero store it in a unit array under a unique index and change ownership to neutral, hide it and then set the active hero to the fresh hero.

If they buy another hero, you simply have to check if there is one stored in the array under that hero type's slot and if not do above. If there is one you remove the fresh hero and simply set the old hero as the new one from the array (ofcourse unhiding it).

o0 Variables :x I'm reading up on the variable tutorial and trying to understand them, thanks I'll see if I can get that working. Wish me luck.

Variables basically store a value for later use. An array is multiple single variables stored in 1 via use of a location integer which allows you to select which variable in the array to store a value to.
