Sorry for all the questions - I've tried to download the definitive editing guide from the thread above but it just says "cannot find server" or "page not found".

Anyway, I have a question regarding counters. Namely, how the flip do I get them to reset?
I have a doorway that opens when four coins are inserted into a coin slot. Every time a coin is inserted, a counter is increased by 1 and when it reaches four the door opens. When the party leaves the room, the door closes again and they need to pay 4 coins to get back in each time. But how do I reset the counter to zero so that it starts counting again when the next coin is inserted? Seems a pretty simple requirement of a counter - I had imagined, logically, that since activating the counter increases it, deactivating it would decrease it. But when I add a line to the counter to deactivate itself the game crashes.

you cannot reset counters but for your case, i would make it with a trigger activating 4 relays. each relay deactivates the counter.
BUT this trigger must be active if you have paid 4 coins... and that's a big problem : you cannot activate/deactivate triggers...

is there a max times you can return, if so use multiple coin slots and destroy them one at a time and activate a new one as they are used, maybe

Counters count DOWN from the number specified. When they reach zero they perform the action. Any non-zero value performs the opposite. They don't work exactly how you might imagine, and you definitely can't reset them.

Ahhhh! So simple with DSAs..

Lol, stop going off topic and pimping for CSBwin converts on the RTC boards! *shakes head*

Could not help myself when two simple problems
arose simultaneously. Sorry.

I worked it out in the end.
I was right - Activating a counter counts up (or down according to what I read here) and deactivating it counts down (or up).

The problem simply seems to be that a counter can't deactivate itself without crashing the engine. I can't think why.

Anyway, the solution was to have the counter activate a relay when it reaches it's count. The relay simply deactivates the counter four times. Works like a dream.

I eat humble pie!

There's more info on counters in these threads:

I believe you need t take more advantage of multiple relays to smooth out some of the counter functions...haven't played around with this for ages
