Pingus tunneling through blockers #28

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm playing svn revision 3985 of pingus.
Find attached a demo of
pingus/data/levels/playable/if_only_i_can_fly_-_wayne_shelley.pingus
where the pingus are sort of tunneling through a row of blockers.

The problem is caused by blockers having overlapping capture ranges, thus two 
blockers with a walker in the center will result in the blocker on the left 
overwriting the command from the blocker on the right.

A potential solution would be to calculate the real direction of a pingu (i.e. 
pos - last_pos) and using that for decision making instead of the direction 
variable, which is changed by the blockers. Saving the last direction and using 
that might work too.
