So if our character moves far enough, the leg should reposition itself in a believable fashion and to a valid location. We know that our main goal is to have the legs move as if they are driving the movement of the lizard. Next up, the real meat of the procedural movement operation, the leg movement.īefore starting out it always helps to break down the problem in to smaller sub problems and to set clear goals. It comes with a set of premade systems that are useful for common setups such as humanoid characters but the real interesting part is the ability to create your own, fully custom IK setups and constraints.īelow you can find an example of our basic look at configuration: It’s a feature complete IK solution created for Unity that offers the flexibility to basically create any IK setup that you want. In Trifox we use Final IK for all our IK setups and needs.

In those cases you can either decide to write your own IK system, use a free solution that can be found on the web or use an asset store package dedicated to IK systems. So when you are dealing with more exotic characters that for example have multiple sets of legs or that require longer bone chains you may not always be able to achieve the results that you want. The only downside is that this implementation only works for humanoid bone structures. Unity (the engine we use for Trifox) actually comes with a build-in IK solution. Which is a variant of an IK system specifically set up for bone chains that need to curve/rotate towards a specific point.Īs if the bones are looking (hence the name) at that point in the distance. Having a character look at a point of interest.

Having a character press a button without knowing how the player will be positioned in front of the button.

(foot placement on a staircase or rough terrain)

Making sure the footplacement of a character follows the orientation and height of the ground and obstacles.

If you aren’t familiar with the technique, in short, instead of creating an animation by rotating each bone of the character manually, we inform the IK system of our desired end position and let the code/math do the work for us.Īs you can imagine, IK systems are super cool and come in really handy when you want to have dynamic animations that interact with the environment. In order to achieve this effect we make use of a technique called Inverse Kinematics (IK). The only way forward was clear … it was time … time to enter the world of With limited time and budget in mind, non of these routes seemed like a viable option to tackle our problem. It would also require a number of setup changes, something that we would rather avoid.īoth solutions have the requirement that the rotation speed, movement speed and animations need to be finely tuned to eachother.Īny change to one of these elements could break the setup and require a rework of the animations. But that wouldn’t be a guaranteed success and it could bring with it a whole other set of issues.

Another solution would be to alter the movement system.

Spending a long time creating the perfect animation set for each possible situation.

We could add a whole bunch of inbetween animations that would help solve this problem.

However, during transistions and with variable movement speeds the sliding of the feet on the surface isn’t something that looks or feels all that amazing. When you get the correct movement speed going everything is great. Especially when dealing with a lot of back and forth. It doesn’t really sell the transistion from one direction to the other by just doing the animation blend.

There’s no real history to the tail movement.

That way the character would always turn in an arc instead of doing an in place 180° direction change.

For example running backwards.įor the character curling that is showcased in the animation to be usable, the movement should always be handled in a single direction (forward of the character) and the rotation should then be in full control of the direction. This means that the movement direction can be doing one thing while the rotation/orientation of the character is doing something completely different.

In Trifox our characters have independent movement and rotation control. First off the rotation would require the movement logic of the character to be handled differently.There are a couple of issues that really stand out: Not so great… So what is going wrong here?
