How to Cast AOE Spell like Blizzard?

I try this

but it won't work
Here is how I do it :
call HandleTerrainClick and then call Lua function CastSpellByID
But nothing happened.
Is there any hints? Thanks!~

hm. tbh never tried this. but what about doing it just like a player would do it?

1. cast spell
2. send the terrainclick

would somehow make a little bit more sense in that order

Cast spell. Click terrain.

Works flawlessly for me.

I assume you are trying to do this for botting purposes, so my answer probably isn't relevant.

I wanted to create a single hotkey that would use my frost trap (trap launcher) and launch it at my current mouse position, so I did the following: (Probably could have done it better, but it works for me!)

            clsMyMemory.DoString("CastSpellByID(77769)"); //Trap Launcher
            Thread.Sleep(300);
            clsMyMemory.DoString("CastSpellByID(82941)"); //Ice Trap(Frost - Trap Launcher)
            Thread.Sleep(100);
            clsMyMemory.DoString("CameraOrSelectOrMoveStart()");
            clsMyMemory.DoString("CameraOrSelectOrMoveStop()");

Two things to note:
1)The 300ms delay is only because Trap Launcher sends a cast to the server to get the buff that allows you to cast the trap launcher version of the trap. Its probably better to handle this with a loop to check UnitBuff("player", "Trap Launcher") but I was being lazy when I was writing this.
2) I am not so sure how necessary the 100ms sleep is, my thought when I was writing this is that I would have to give the client time to register that the spell was ready to cast before trying to click the terrain. This may or may not be necessary.

EDIT: Btw, wouldn't you have to call TerrainClick AFTER calling CastSpellByID? Your OP has it the other way around.

I send a CMSG_CAST_SPELL packet with the target coördinates.
