        "AbilityChannelTime"    "3"
    }```
```lua
engineer_teleport_use = class({})

function engineer_teleport_use:OnSpellStart()
    self.channel_time_elapsed = 0
    print("Test1")
    self:SetChanneling(true)
end
function engineer_teleport_use:OnChannelThink(interval)
    self.channel_time_elapsed = self.channel_time_elapsed + interval
    print(self.channel_time_elapsed)
end

function engineer_teleport_use:OnChannelFinish(bInterrupted)
    print("Test3")
end

You don't need manually SetChanneling your channeling ability for it to be channel, CastAbility() looks like some valve internal thing. Try caster:CastAbilityNoTarget(...) or just execute cast order (order should work correctly)

mhm, what am i doing not correctly ?

local options = { UnitIndex  = unit:entindex(), OrderType = DOTA_UNIT_ORDER_CAST_NO_TARGET, AbilityIndex = teleport_use_ability:GetEntityIndex()}
DeepPrintTable(options)
ExecuteOrderFromTable(options)```
```{
   UnitIndex                           = 193 (number)
   OrderType                           = 8 (number)
   AbilityIndex                        = 246 (number)
}``` 
but ability doesnt cast

That's weird. I don't think you should need to do queue = true unless your unit has some thinking logic that causes it to be overridden

It being a queue might have issues later on, so it's probably better to check it properly. If you have a thinker, you might want to check whether it should issue orders. Maybe if it is currently casting an ability, it should just return?

[quaint frigate]

He is doing something like portal, it need to listen the OnOrder event, but here's the thing
OnOrder means unit is executing some order
and with some weird order mechanics, the unit ignores the queue-jumping order
so you need to push the order to the queue (Queue = true

[iron fractal]

twin gates can be created with underlord portal base class and changing ability index in order filter i think it easiest way

[frosty parcel]

Oh got it, that makes sense

The correct way I think for this would be Order Filter though
