#242 need a EvacAllowed function

Need the ability to lock evac spells in zonescripts... will also probably need a EvacAllowed check for spell scripts

Fixed, requires SQL Change

ALTER TABLE zones ADD COLUMN can_evac INT NULL DEFAULT '1' AFTER can_gate;

Added 2 lua functions: int EQ2Emu_lua_SetCanEvac(lua_State* state) int EQ2Emu_lua_GetCanEvac(lua_State* state)

Example code is in spells/scout/escape.lua and below:

function precast(Caster, Target)

if(GetCanEvac(Caster) == 1)
then
    return true   
else
    SendMessage(Caster, "You cannot use evacuate spells in this zone.", "red")
    return false
end
return true

end
