Can't limit spell fire...

[MurDocDoc]

Hello GameMaker Community,i'm new to Gamemaker and i wanna make a small RPG game.
I have 2 issues that's been bugging me for the last 3 days.First one and the most annoying ... can't limit spell fire.
I implemented mana variable etc,it consumes all the mana upon fire (mana regen works) but i can fire all the time(even when mana is 0/10).....
Second issue is how to put different damage values to different swords.(I use sprites to pick weapon for the ground and replace it..). Please ,need help !

What code are you running inside Alarm 0?

Also for the second question need a bit more information about your set up. If you're using sprites for swords, would need to know what object, if any is managing those sprites.

Checking mana value when the projectile is already created is rather unconventional, but whatever.

Spoiler: Creation event for projectile

if( obj_player_stats.mana >= 5 ){
obj_player_stats.mana -= 5;
//create whatever particles
alarm[0] = room_speed/8;
obj_player_stats.alarm[1] = room_speed*2;
}
else
{
instance_destroy();
}
