Scripts for beginners.

Hello. Can anyone help me with a script? I don't understand how the StartCombat command works at all. For example, I want a message to appear when entering a region, and then a battle to begin. I came up with the following script:

 

function Region1F()
   
    sleep(5);
    MessageBox("/Maps/SingleMissions/MapochkaTEST3/battletext.txt");
    sleep(5);
    StartCombat("RedHeavenHero04", "Ottar", 4, 166, 100, 166, 100, 167, 75, 169, 50, 170, 15);
    Trigger(REGION_ENTER_AND_STOP_TRIGGER,"Region1",nil);
end;
Trigger(REGION_ENTER_AND_STOP_TRIGGER,"Region1","Region1F");

 

But it doesn't work - the message appears, but the battle doesn't start.

 

And my second question is - how can I make creatures play animations on the map? For example, I want two stacks of creatures on the map to play attack animations against each other. Please tell me how I can implement this.

 

Thank you in advance.
