controller stucks in the air on slopes

[Soamp]

Hi,

I've a problem with controller. my controller works fine on flat terrains but it gets problematic when it's on a slope.

you can see it in attached pictures. one side of controller stays on the terrain and it keeps the other side in the air!

as you can see in pictures, its right leg is on the terrain when its left leg is in the air!

 

Is there any way to fix this problem?

Can I "AlignToGround" my controller? If yes, How?

 

Thanks in advance

Hi, Thanks for your reply

I use a prepared animation for walking and use Animate command to play it while my character is walking, so character's bones are being controlled by the animation. If I use IK to modify the position or rotation of a bone then my animation would not be played correctly.

 

is there any other way to fix it?

 

thaks.

It's complicated to sort out and I haven't quite managed it yet. This problem is common to most games, search out youtube for examples of floating characters in AAA games.

Not really, if you are relying on key frame animation alone then you would need to produce animations for every possibility and apply those as and when required. This is not only a lot of work but requires standardisation of your level design for example ... slopes all have to have the same angle so you can apply your 'walk on slope left leg down animation', 'walk up slope feet at 35 degrees' animation and have them look right.

 

As Chris says, even some of the big game houses don't bother solving this. Those who do tend to go for combinations of extra animations and coded real time manipulation of the animations (IK and advanced animation blending techniques).
