Delta Loc/Rot/Scale Ipo curve are now supporting in the BGE with the following limitations: 1. All Ipo channels are now independent. In Blender 2.45, all 3 Loc Ipo channels were automatically set together. For example, having just a LocX Ipo channel was sufficient to fix the X, Y and Z coordinates, with the Y and Z value taken from the object original Y and Z location in Blender. The same was true for the 3 Rot and the 3 Scale Ipo channels: the missing channels were assumed to have constant value taken from the object original orientation/scale in Blender. With this patch, all Ipo channels are now independent. THIS WILL CREATE BACKWARD COMPATIBILITY PROBLEM if you omit to define the 3 channels of a same type together in your Blend file: the undefined Loc, Rot, Scale coordinates of the object will be influenced by the parent/spawner Loc/Rot/Scale in case the object is a child or dynamically created. 2. Delta Loc, Rot, Scale are now supported with the following limitations: - The delta Loc/Rot Ipo modify the object global (NOT local) location/orientation - The delta Scale change the object local scale - The delta Ipo curves are relative to the object starting Loc/Rot/Scale when the Ipo was first activated; after that, the delta Ipo becomes global. This means that the object will return to this initial Loc/Rot/Scale when you later restart the Ipo curve, even if you had changed the object Loc/Rot/Scale in the meantime. Of course this applies only to the specific Loc/Rot/Scale coordinate that are defined in the Ipo channels as the channels are now independent. 3. When the objects are converted from Blender to the BGE, the delta Loc/Rot/Scale that might result from initial non-zero values in delta Ipo Curves will be ignored. However, as soon as the delta Ipo curve is activated, the non-zero values will be taken into account and the object will jump to the same Loc/Rot/Scale situation as in Blender. Note that delta Ipo curves with initial non-zero values is bad practice; logically, a delta Ipo curver should always start from 0. 4. If you define both a global and delta channel of the same type (LocX and DLocX), the result will be a global channel equivalent to the sum of the two channels (LocX+DLocX).

BGE logic patch: new "Add" mode for Ipo actuator, several corrections in state system. New Add mode for Ipo actuator ============================= A new Add button, mutually exclusive with Force button, is available in the Ipo actuator. When selected, it activates the Add mode that consists in adding the Ipo curve to the current object situation in world coordinates, or parent coordinates if the object has a parent. Scale Ipo curves are multiplied instead of added to the object current scale. If the local flag is selected, the Ipo curve is added (multiplied) in the object's local coordinates. Delta Ipo curves are handled identically to normal Ipo curve and there is no need to work with Delta Ipo curves provided that you make sure that the Ipo curve starts from origin. Origin means location 0 for Location Ipo curve, rotation 0 for Rotation Ipo curve and scale 1 for Scale Ipo curve. The "current object situation" means the object's location, rotation and scale at the start of the Ipo curve. For Loop Stop and Loop End Ipo actuators, this means at the start of each loop. This initial state is used as a base during the execution of the Ipo Curve but when the Ipo curve is restarted (later or immediately in case of Loop mode), the object current situation at that time is used as the new base. For reference, here is the exact operation of the Add mode for each type of Ipo curve (oLoc, oRot, oScale, oMat: object's loc/rot/scale and orientation matrix at the start of the curve; iLoc, iRot, iScale, iMat: Ipo curve loc/rot/scale and orientation matrix resulting from the rotation). Location Local=false: newLoc = oLoc+iLoc Local=true : newLoc = oLoc+oScale*(oMat*iLoc) Rotation Local=false: newMat = iMat*oMat Local=true : newMat = oMat*iMat Scale Local=false: newScale = oScale*iScale Local=true : newScale = oScale*iScale Add+Local mode is very useful to have dynamic object executing complex movement relative to their current location/orientation. Of cource, dynamics should be disabled during the execution of the curve. Several corrections in state system =================================== - Object initial state is taken into account when adding object dynamically - Fix bug with link count when adding object dynamically - Fix false on-off detection for Actuator sensor when actuator is trigged on negative event. - Fix Parent actuator false activation on negative event - Loop Ipo curve not restarting at correct frame when start frame is different from one.
