source: orxonox.OLD/trunk/src/lib/graphics/effects/lightning_effect.cc @ 9109

Last change on this file since 9109 was 9006, checked in by bensch, 18 years ago

orxonox/trunk: merged the mountain_lake branche back to the trunk
merged with command:
svn merge -r8799:HEAD https://svn.orxonox.net/orxonox/branches/mountain_lake .

conflicts in script taken from the branche, since they are indentation-problems.

also fixed the delete-bug for the lightning-effect
