Entity not Functioning in Air

[FreeTacos.exe]

I can't seem to get this entity I scripted to function only on the ground and not when it is in air. I tried to create a tracer and use the "OnGround()" code, but it is all to confusing. What I'm asking for is if there is any code that will prevent my function from activating in air. Here is my original code, but I realized if I used a tracer, it would only function on the ground. I want the entity to function on any surface whether it is a prop, entity, or just the ground. I only want the entity not to function in the air.

function ENT:Think()
	local trace = { start = self:LocalToWorld(self:OBBMaxs()), endpos = self:LocalToWorld(self:OBBMins())}
	local trace1 = util.TraceEntity( trace, ent ) 
	if ( trace1.HitWorld ) then
		local Roll = self.Entity:GetAngles().roll
		if Roll < 90 && Roll > -90 then
			self:AttemptJump()
		else
			self:AttemptFix()
		end
	end
end

if (trace1.Hit)

You might prefer a hull trace

(Anyway, I don't know if hulltraces will make the entity seem on the ground even if it's just slightly above it)

Edit: I did some debugging (Using util.TraceEntityHul and util.TraceEntity --- No Difference)

Test 1: Slightly above ground
Results: The script says the trace hit the ground, despite the two debug spheres saying it's rather impossible (They mark endpos and start of the trace)

The entity still functions in air if I use a trace hull.

function ENT:Think()
	local trace = { start = self:LocalToWorld(self:OBBMaxs()), endpos = self:LocalToWorld(self:OBBMins())}
	local trace1 = util.TraceHull( trace )
	if (trace1.Hit) then
		local Roll = self.Entity:GetAngles().roll
		if Roll < 90 && Roll > -90 then
			self:AttemptJump()
		else
			self:AttemptFix()
		end
	end
end

[Rubat]

 local trace = { start = self:LocalToWorld(self:OBBCenter()), endpos = self:LocalToWorld(self:OBBCenter()) + Vector(0, 0, -16000), filter = self}
local trace1 = util.TraceHull( trace )

Thanks you guys, I got it working.
