This is a temporary fix, but a complete fix will require a rewrite of of some part of the where_is_object function, and that would take too much time before 2.31.
This is done by disabling the object position refresh call when calculating these constraints. From the tests I did, this doesn't cause any problem at all.
The main point of this is to create pistons and the like.
For coders:
the detect_constraint_loop function now takes an additional parameter that determines the constraint type of the object it's looping from.
Axis options for TrackTo
LockTrack
FollowPath
Auto creation of TrackTo constraint from Ctrl-T (old track still an option)
Auto creation of FollowPath when parenting to path (Normal parent still an option)
Backward compatibility stuff to convert the per object axis settings to per constraint when a Track constraint is present.
Function to convert old track to constraint (commented out)
Revamped the constraints interface with Matt's work from tuhopuu and the stuff we were discussing earlier.
--------------------
For coders:
unique_constraint_name and *new_constraint_data moved to the kernel (constraint.c)
new Projf function in arithb gives the projection of a vector on another vector
add_new_constraint now takes a constraint type (int) parameter
add_constraint_to_object(bConstraint *con, Object *ob) to link a constraint to an object
add_constraint_to_client(bConstraint *con) to link constraint to current client (object or bone)
add_influence_key_to_constraint (bConstraint *con) to (eventually) add a keyframe to the influence IPO of a constraint
include only (use BIF_interface.h instead)
- split up interface.c in two files: NEW: interface_panel.c
- removed the temporal text files
WARN: FIX AUTOMAKE AND MSVC!
First, check on the new files, which are listed below.
The new butspace.h is a local include, only to be used for the buttons
drawn in the buttonswindow.
- editbuts, animbuts, gamebuts, displaybuts, paintbuts, work now
- i quite completely reorganized it, it's now nicely telling you what
context it is in
- sorting error in panel align fixed (tabs were flipping)
- align works correctly automatic when you click around in Blender
- editsca.c renamed to buttons_logic.h
- button names are truncated from the right for allmost all buttons
(except text buttons and number buttons)
- while dragging panels, you cannot move them outside window anymore
And of course fixed loads of little bugs I encountered while testing
it all. This is a version I really need good test & feedback for.
Next step: restoring material/lamp/texture/world
