I've got this character in Unity3D (2D Mode)... in a a slope which looks like this, enter image description here

But I want the character to stand along the red line..Like below enter image description here

How can I make it in Unity3d?

I've got this setup..

enter image description here

I'm using simple Addforce for movement... If I remove the z position constraint it results in weird movement like rolling and so on.... Any help would be appreciated :)

Have you considered that it looks very odd for a person to standing perpendicular to a slope?

standing perpendicular to a slope

You need to be upright to stay in balance.

Some alternatives:

  • Treat his feet as a separate object and rotate them to be parallel to the slope. (A raycast will find the angle's normal, as dnk described. The angle for the feet is that + 90°.)

    rotated feet

  • Fake it, by moving the whole character a little downwards.

    \$\begingroup\$ That also suggests that as soon as the rotated feet do not look nicely any more, your character should stumble :) \$\endgroup\$ Commented Sep 6, 2015 at 7:16
  • \$\begingroup\$ :-/ Does the rotation of the feet look odd in the picture I attached? \$\endgroup\$

    \$\begingroup\$ You don't need to move the character downwards just move the visual of the slope upwards a bit relative to the physical \$\endgroup\$ Commented Sep 6, 2015 at 14:19

Try using RaycastHit.normal on ground to get normal. Them put char.up = normal

    \$\begingroup\$ Why waste CPU with a raycast if the Unity physics already gives this information by default on every collision? \$\endgroup\$
