The Target is what we use to animate the IK – the Solver will try to reposition the Effector where the Target is. The Effector is the bone that the rest of the bones be calculated based on its position.Ĭlicking on Create Target will create our IK. We drag the Front hand bone to the Effector field. I renamed it to Hand-F-IK, as I want it to control the Front arm bones. Selecting this IK solver will create a new game object. Clicking ‘add to list’ presents 3 IK solver options, each using a different algorithm to calculate bones’ position.įor this character, we will use the Limb IK solver – a standard two bone Solver that is ideal for posing joints such as arms and legs. With this component, we create and control our IK. We start by selecting the character’s root object and adding an IK Manager component. With IK, we can add inverse kinematics to our character, making the animation process much more comfortable.įor this type of character, the IK will work best on the legs and arms. Our last step before starting to animate is to add IKs. The Smooth mode gently smoothes the gradient between bones’ weights.ĭragging the character to the scene, we can see the bones we just created and the sprites. The mode ‘Add And Subtract’ adds the influence of a new bone, while the mode ‘Grow and Shrink’ changes the weight balance between bones already influenced by the selected bone. With the Weight Brush option, we can use a brush to adjust the weights. We now have lovely gradients representing the weights’ division. As we connected our bones in the previous step, uncheck it, and generate. We can either generate Weights with or without associate bones. The easiest way is to use the Auto Weights option. Weights allow transformed bones to deform the mesh automatically. To make the bones influence the sprite vertices, we need to add Weights. While Unity Jobs helps, we should always keep an eye on the performance. Though the same as before, the fewer the bones in one character, the better for your game’s performance. Of course, one sprite can have as many bones as you like. Select a sprite in the Visibility window and attach to it a marked bone. With the Bone Influence option, we can select a sprite and add bones to influence it. Keep in mind that complex meshes can reduce performance ideally, we would want to use as few vertices as possible. We can go to each sprite and rearrange, add or reduce the vertices.

The simplest way to add Geometry is by the Auto Geometry option. Geometry, also known as meshes, allows a polygon to be defined inside an image, creating vertices to manipulate bending and deform the sprite. Now it’s time to connect our bones to the sprite.įirst, we will need to add Geometry to the sprites. Higher numbers for bones near us, like the front arm and leg, and lower numbers for bones distant from us, like the back arm and leg.

Since the character’s body occludes an arm and a leg, I made sure to treat them with the bones they deserve.Īt the Visibility window, you can see the bones’ names and hierarchy. A great way to make sure two bones have the same angle.

I went ahead and fully rigged the character.įor some bones, I used the Split Bone option to split them into two. Choose the bone you want to change and drag it under any other bone. Here we can control our bone’s order, names, and depth. Want to change a bone’s parent? We can do that at the Visibility tab. This faint line represents their connection, and you can double-check your bone layout at any time. With Unity, once we place a bone, the second one is automatically set as its child, but we can change that clicking on a bone will mark it as the parent of the next bone we will create. With this character, we want the arms and head to follow as we move the torso bones, and for that, we will need to make the torso bone their parent. When we move it, it will drag the child bones with it. When creating a rigged character, it is important to pay attention to the bones hierarchy.Ī parent bone is the origin of the other connected bones.

Regretting creating a bone? You can delete it by pressing Delete on Windows or Command + Backspace on Mac. If we want to edit an existing bone’s position or length, we can either use the Edit Bone button or click on the bone’s anchor to move the bone as we like. And with a right-click, we end the bones’ chain. A second click will complete the current bone and begin creating the next one. By clicking once and moving our mouse, we can control the bone’s lengths and engle. We draw bones over our character by selecting Create Bone and click to place a bone.
