Changeset 6746 for code/trunk/src/libraries/core

Timestamp:

Apr 16, 2010, 2:50:16 PM (15 years ago)

Message:

Merged gamestates2 branch back to trunk.
This brings in some heavy changes in the GUI framework.
It should also fix problems with triggered asserts in the InputManager.

Note: PickupInventory does not seem to work —> Segfault when showing because before, the owner in GUIOverlay::setGUIName is already NULL.
I haven't tested it before, so I can't tell whether it's my changes.
