The two main tools used to animate characters are the Transform and Inverse Kinematics tools. Harmony provides different tools for animating cut-out characters and trajectories. IK only works on a hierarchy where the pivots are properly set. Inverse Kinematics will not work on basic rigs without hierarchy because there is no hierarchy chain present.

Inverse Kinematics in Harmony uses the connection between each of the parts' pivots. Harmony uses the rigging hierarchy already created in the Timeline view, so there is no need to place bones in the character. In most 3D animation software, Inverse Kinematics is implemented as a skeleton system. It will also assist you with posing difficult moves. This tool is useful when you want to bend a character's knees, make it sit and move the rest of the body, and so on. However, you don't have to use IK every time you have a hierarchy rig. It can be used on any piece connected in a hierarchy. Leg.The Inverse Kinematics (IK) tool allows you to pull on a character's extremities, such as the hands and feet, and have the rest of the body follow.

The code for this is a one liner function ProceduralAnimatorClass:MoveLegs(stepCycle,dt)

You can try replacing it with the classic 2 joint and 2 limb inverse kinematics as the code artifically creates an additional limb for R6 to make the R6 pretend it has a knee to raise “Up”. Implementing this is left as an exercise to the reader. However, it is possible to “jump out of” concavities by adding large random offsets to each joint, and then attempting the IK solve again. These concavities are impossible to avoid in a heuristic IK algorithm (read: all of them except Analytic ). You could also reset the C0 of the limbs once in a while in order to make the CCDIK start from the baseline position and reset the rotations locking it in a “weird place”. This is also the reason why it is not compatible with Animations. Local goalCF = bounceCFrame*waist1*ANGLES(swayX,swayY,sway):inverse()įor sorry for the lack of reply, the legs being funky and not reaching the goal in a nice manner has to do with the inverse kinematics method, it’s iterative and doesn’t generate a 100% solution towards the goal it guesses and tries and doesn’t care if it looks weird or not TL DR. Local swayX = math.rad(relv1.Z)*0.5*self.SwayX

Local swayY = 0.1*s(self.WaistCycle)-2*math.rad(relv1.X) Local bounceCFrame = CFrame.new(0,self.WalkBounce*s((self.WaistCycle+90+45)*2),0) function ProceduralAnimatorClass:MoveTorso(stepCycle,dt10,rootVelocity) Modifying the WastCycle will mainly change the timing of when the bounce happens, such as it bounces up when the leg is being raised up. If the following conditions are not met, your edits to the script may not be distributed.Īll the actual movement is done in the ProceduralAnimation class which creates the goal target for the inverse kinematics as is within the video.Īnd the sway controls the rotation side to side, it’s been set to some arbitrary value try playing around with it or removing it entirely.
