Problems with leaks

I have a problem with a triggered spell, when I use the spell for about 5-6 times it creates lag. I think the problem is the leaks but I'm not good at clearing Leaks even though I read all the tutorials I found.

Triggers:

• Start Ray
• Events
• Unit - A unit Starts the effect of an ability

• Set Ray_Caster[(Player number of (Owner of (Casting unit)))] = (Casting unit)
• Set Ray_Angle[(Player number of (Owner of (Casting unit)))] = (Facing of (Casting unit))
• Set Ray_Point[(Player number of (Owner of (Casting unit)))] = ((Position of (Casting unit)) offset by 50.00 towards Ray_Angle[(Player number of (Owner of (Casting unit)))] degrees)
• Set Ray_Timer[(Player number of (Owner of (Casting unit)))] = 0.00
• Trigger - Turn on Channel Ray <gen>

• Then - Actions
• Player Group - Remove (Picked player) from Ray_Casters
• Unit Group - Remove all units from Ray_Victims[(Player number of (Picked player))]
• Custom script: call RemoveLocation (udg_Ray_Point[GetConvertedPlayerId(GetEnumPlayer())])
• Trigger - Turn off (This trigger)

• Then - Actions
• Unit - Cause Ray_Caster[(Player number of (Picked player))] to damage (Picked unit), dealing Ray_Damage[(Player number of (Picked player))] damage of attack type Spells and damage type Normal
• Unit Group - Add (Picked unit) to Ray_Victims[(Player number of (Picked player))]
• Else - Actions
• Else - Actions
• Do nothing
Can someone take a look and give me some advice please? (or the leak-less versions)

I attached a map with this spell only and it does not lag, I suppose that it lags only on bigger maps.

Things that leak explains everything, about how to get rid of leak in GUI.

Going deeper: This is a good tutorial if you wish to make your spells MUI. MUI means that multiple units can cast the same spell during the same time without any bug issues.

Those lines leak:
• Set Ray_Point[(Player number of (Owner of (Casting unit)))] = ((Position of (Casting unit)) offset by 50.00 towards Ray_Angle[(Player number of (Owner of (Casting unit)))] degrees)
• -------------
• (Distance between (Position of Ray_Caster[(Player number of (Picked player))]) and Ray_Point[(Player number of (Picked player))]) Greater than or equal to Ray_Distance[(Player number of (Picked player))]
• -------------
• Unit Group - Pick every unit in (Units within 150.00 of Ray_Point[(Player number of (Picked player))]) and do (Actions)
Each time you see "Position of", it is reference to location which has to be stored and removed once not needed. With group, use either of methods presented in Things That Leak.

Your scripts quickly generate multiple leaks each second, however, the lag issue could be also caused by high rate of iterations with GroupEnum/ForGroup/CreateUnit functions. Usually we try to simplify algorithm/approach to achieve better efficiency e.g instead of creating 1 unit per target, create 1 dummy per iteration and apply timed life to it later, after all the casting is done.

Next, you spam calls left and right without actually storing data that is used throughout the code i.e (Casting unit), (Owner of (Casting unit)), (Picked Player). Use locals or globals - if u are more convenient with them - as a reference for such objects: e.g temp_u = (Triggering unit), temp_p = (Triggering player). And yes, you can use Triggering unit instead of casting. Same goes with player.
