This may have been answered, but I can't search the forum . . . How do you make instant upgrades of towers possible when you are designing your own map?

Also - anyone else can use this thread for map editing tips or questions.

the only thing that comes close to this is: not to disable the custom upgrades for faster upgrades.

so the only way to speed upgrading up is in the hands of the players. the map maker can only slow that down again to default by disabling custom upgrades.

Just set the upgrade time to 1 and the upgrade increment time to 0 to have instant upgrades for all players in your map.

that's for the sell time :)

a feature like that for upgrades would be interesting though :D

As lordcrumb said, while you are in the editor the upgrade time is always the default time.
You can speed it up with your skillpoints. If the skill is full you have 4% of the original time left.

oh right, my bad.
