Grounder IK Spider with targeted CCDIK limbs

[Jacob Stove Lorentzen]

Hi Again, after a long hiatus of working on the crab, i'm finally back to try and make it a proper character in our game!

I'm aiming for having our yamato crab walk around on the sea floor while firing at the player, so i'm looking to make sure that its legs dont pierce the ground too much. The area is fairly sloped so i can't just bake the animation.

As far as i understand, the grounder IK system should hook in nicely with my current CCDIK setup, but it does not seem to work the way i want it to:

Here it's above the ground, following the CCDIK target, the Grounder is hooked to the CCDIK

I was thinking the last part of the CCDIK chain would stop at the ground, but i'm probably doing something wrong.

The idea is to animate a walk cycle in unity, and have the grounder help retarget the Y to fit the ground.

Any ideas?

I notice the tips of the feet react when i move the main body, or the feet around,  is the grounder only trying to move the position of the last thing in the IK chain?

Hey,

Can you send me that spider rig so I could take a look?

I don't quite understand what's going on, do you have baked animation for the spider or are you making it all procedurally? The Grounder works on top of normal baked animation, moving the feet up/down using the IK chains that are assigned on top of it.

Cheers,

That's what's wrong then, i wasnt using baked animation, but i was planning on animating it in unity using the CCDIK chain targets and the animator. (Ghetto IK handles)

However! I tried moving to a completely procedural approach, similar to the mech-spider demo, and its working like a charm. I'll post a webm here later once its complete.
