This might work, but I dunno how .visible works with sprites.

#=================================
class Scene_Map
alias wyatt_edit_update update
def update
if $game_switches[EDITHERE]
@hud.visible = true
else
@hud.visible = false
end
wyatt_edit_update
end
end
#=================================

Add it somewhere below that script, and change the words "EDITHERE" to the number of the switch.

 

[Hairdude]

Hmm, I get a syntax error when I try that.

 

[Ellie]

I missed a line out Fixed it.

 

[Sarkilas]

.visible works with sprites. Now that's confirmed. The script's fine, there can't be any errors if the @hud object exists, and it does, so if you still get an error it can't be caused by Wyatt's script.

 

[Hairdude]

ok. thanks for reply, the script doesn't cause any errors now
but the hud disappears completely now, even if i turn on/off the switch.

any other ideas?
