Making the player fly like noclip but with collision

Hello,
I was wondering if there would be a way of allowing the player to fly like noclip but not able to go through walls/props etc… I have tried changing the movetype to MOVETYPE_FLY, MOVETYPE_FLYGRAVITY and MOVETYPE_LADDER

Thanks, rtm516

Try taking a look into uclip code

Thanks been looking for something like this, will report back if i can get it to work.
