Character Jump

Alright guys, right now I’m creating a test game to see how my skills have improved and just to overall give myself some practice.

My problem is, when my character jumps and moves in the air or even when he stays stationary, He goes past the floor object I have him hittesting with.

I’ve provided the fla file so can check it out, hopefully someone can help me(btw its in *.zip format)

I’ve even tried adding on after it find the hittest, this._y = #; but it still doesnt work

thanks for your time if you can assist me

*Btw, all the coding is on the main timeline on the frame Actions
