Help with a JASS trigger

[RagnarawK]

I have almost no clue how JASS works and I would like to modify a trigger but don't know proper operations and/or functions to do it. I would like to make the

function Trig_Parachute_Conditions takes nothing returns boolean
	return GetSpellAbilityId() == 'A007'
endfunction

function Trig_Parachute_Actions takes nothing returns nothing
	local integer PlayerId = GetPlayerId(GetOwningPlayer(GetTriggerUnit()))
	local integer ObjId = udg_playerControlledObj[PlayerId]
	local unit Obj = udg_objUnit[ObjId]
	local real Scale
	if udg_objZ[ObjId]-GetEnvironmentHeight(udg_objX[ObjId],udg_objY[ObjId],udg_classCollision[udg_objClass[ObjId]]+1,0)>0 then
		if udg_objParachute[ObjId]==null then


[change section]			set udg_objParachute[ObjId] = CreateUnit(Player(PlayerId),'h008',GetUnitX(Obj),GetUnitY(Obj),GetUnitFacing(Obj))
			set Scale = udg_classCollision[udg_objClass[ObjId]]/145+0.22
			call SetUnitScale(udg_objParachute[ObjId],Scale,Scale,Scale)
			call SetUnitUserData(udg_objParachute[ObjId],-1)
			set udg_objParachuteEffect[ObjId] = AddSpecialEffectTarget("parachute.mdx",udg_objParachute[ObjId],"origin")
			call ShowUnit(udg_objParachute[ObjId],false)
			call AdjustParachute(ObjId,true)
			call ShowUnit(udg_objParachute[ObjId],true)[end change section]


		endif
	else
		set udg_objSpeedZ[ObjId] = 8.8
	endif
endfunction

separated text into a glide, where movement is still possible but falling is still slowed. I am working on a Combat Zone mod and can post any additional code or the map if nessecary.

Care to explain a bit more? From that trigger, it seems like nothing would limit movement. (Unless you mean that the parachute doesn't follow the unit)

Also, post function AdjustParachute if you can. =)

It might help to just post the map, all this is kinda alien to me. My goal is to change the parachute function of slow falling (which also disables movement, which can only be done with the arrowkeys) into a gliding function, with either arrowkey steering or just foreward movement. Sorry if i'm being vague, i'm pretty confused by all of this. I'll post the map or some code sections in an edit later.
