- renaming "st-bolder" to "st_boulder"
- abolishing inconsistent message "trigger" by mapping to existing
alternative messages for old API
- new internal message "_trigger" just sent by boulder:
- value true (rising edge): just arrived on neighbour grid - make place or act
- value false (falling edge): relax
- mirror and fourswitch just act on rising edge - they turn just once
- impulsestones do not push back the boulder that triggered them
- boulder reverses dir on laser light from back and front once
- boulder starts faster after init - with blocker items in front and
beneath boulder all initial constellations can be set up that occur in
runtime, too.
- rotator impulses on a blocked boulder will not generate trigger messages
if the boulder does not change direction.
- boulder with two rotators aside will trigger a blocker stone independent
of rotator sequence (boulder could be trapped in 1.01)
- fix r973 black/whitestone: force actor check on signals from items
Note:
- compatibility of existing levels need to be checked
- some triggered objects may be changed from rising to falling edge
