off-center?

so...it appears that if your object is "off center" from its center, then its physics are messed up--meaning that edges of your objects might poke right through other objects, etc.--things you wouldn't anticipate. Courious, but overcome-able thankfully--center your objects [edit mode, "object" menu, :) transform, obData to center].

errors off by one

If you get an error message in blender, it says six, but error's on five, so subtract one. Thanks!

ipo's and parenting

I believe the best way to get the "dynamic 3d avatar" is to have a "fake person" that is attached to a real (invisible) parent, which parent has dynamics associated with it.

Also, it appears that you CAN set object arbitrarily in Blender (see the addObject2.blend example) by using "instantaddobject" and that instantreplacemesh also exists, BTW. Then you can change it more easily on the fly. (call "getlastcreated object" [?] immediately after calling that).

ipo's versus frames

It appears that sometimes frames are "dropped" for whatever reason (the "framedout" message, perhaps?) and when it does not show the frame IPO's don't advance. So this throws off timing a little if you rely on IPO's finishing on time, but hey :-) Now we know.

how to flip normals/invert them

go to edit mode (intuitively enough) and then w, invert

how to do buttons in blender, and also how to set object property names

So--the mouse left guy fires TWICE--once when you click down, once wuen you click up. To check for this in the script run "sensor.isPositive()" or something like that.


You CAN add things to objects on the fly "getOwner().abc = 3" BUT these are reset if the scene is reset (or hard changed, I presume). With scene freezes I'm not sure what happens (!)

So life is good.

how to get blender to not choke when you check for a variable that doesn't exist

try:
print GameLogic.bbc == ""
except AttributeError:
print "bad!"
print "done"

text boxes

It would seem that "text" objects don't appear in the blender game engine. It would appear that you can create a "more intense" one, however. http://download.blender.org/documentation/NaN_docs/BlenderGameReference/bitmaptext.html

empty's bounce

So...make an empty, turn it into an actor, and make it dynamic and...voila! Empty's bounce!
