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.
