WOLF is a CAOS function which controls certain aspects of the engine.
Syntax: WOLF and_mask (int) xor_mask (int)
Returns the new WOLF value as an integer. The new WOLF value is calculated by applying the and_mask and the xor_mask to the current WOLF, in that order.
The WOLF value and the masks are bitmaps made up of the following bits:
- 1. Render display. When turned off, display is only updated when bit 4 is set, and the game runs considerably faster.
- 2. Fastest ticks. Don't limit rate to 20fps, but run as fast as possible.
- 4. Refresh display. If set, display is updated at the end of the tick, and this bit is cleared.
- 8. Autokill.
The default WOLF value is either 9 or 1, depending on whether autokill is enabled or not.
Obviously applying WOLF requires some careful thought. Some obvious examples (which didn't!) follow.
outv wolf 15 0 [current WOLF value, e.g.:] 9 outv wolf 0 0 0 (clears all bits) outv wolf 0 15 15 (sets all bits) outv wolf 15 15 [toggles all bits, e.g.:] 6
- SCOL uses a similar mask system.
