title: Unity 2D Animator, confusion on parameters and transitions for platform 2d character
body: <p>I am new to designing games and have been having trouble for the past couple of days with the animator.  I have downloaded a free asset off the Unity store that included a free sprite character and also its animations for idle, walk, run, and jump.  My issue is when I go to use this asset pack in my game, I can not for the life of me figure out how to transition between idle->walk, and any state->jump.  I believe it has to do with no parameters being set up, as I want the walk animation to occur when my character is moving.  The issue is that it seems to be stuck in idle mode.  In the animator the transitions are set up, but I can not figure out how to let the animator know when I am moving, and when I am actually idle.  How can I connect my characters movement scripts to be used in conjunction with the animation?  Do I need to write a new script, that uses new parameters I make in the animator, or am I completely missing something?  Again I am very new at this, so I apologize if this is a dumb question but I cannot figure it out.  All the videos I have watched only show how to build the animations and put them into the animator, and nothing about the scripts or parameters in specific.  Thank you!</p>
