Creating functions

int DistBetweenObjs(CGObject* ObA, CGObject* ObB)
{
 dx = ObA->PosX - ObB->PosX;
 dy = ObA->PosY - ObB->PosY;
 r = sqrt(dx * dx + dy * dy);
 return r;
};

Let's analyze this:

• Create a function named DistBetweenObjs which returns an integer (int) which takes the arguments:

1. Pointer to a CGObject (expressed by the *)
2. Pointer to a CGObject

• Calculate the X distance between the two objects (simple mathematics here)
• Calculate the Y distance between the two objects
• Calculate the square root of the X distance squared plus the Y distance squared
• Return the square root.
• End the function

As you can see, all the lines end with ";".

Overriding functions

override void CMine::Message(CObject* sender, EMType Type, int MSize, CMessageData* MData)
{
 super;
 if (Type != M_FRAME) return;
 
 for (local i = 1; i < Env->Objs.Count - 1; i+=1)
 {
   local obj = Env->Objs.Objs[i];
   
   if (obj == NullObj) continue;
   if (obj->ClType != OC_Worm) continue;
   
   local worm = CWorm(obj);
   if (ShootData.Team == worm->WormTeam) continue;
   
   
   
   if (DistBetweenObjs(obj, this) < 65)
   {
     PrintMessage(111);
     Active = 1;
     nPulses = 1;
     break;
   }; 
 };
};

• Override the function Message in CMine which takes the arguments:

1. A pointer to a CObject
2. An EMType
3. An integer which is the size of the message
4. A pointer to a CMessageData which is almost unused.

• super; -> Call the original function with exactly the same arguments we have (the game might want to draw or calculate the physics on us)
• Check, if it isn't message for calculations, exit.
• Iterate through every single object
  • If the object is a null object, continue (next object)
  • If the object's type isn't OC_Worm (not a worm), continue (next object)
  • Define a local variable (only usable inside this function) named "worm" which is a CWorm object.
  • If ShootData (CShootDesc)'s team (basically, the team of who fired this weapon) is the same team as our worm, continue (next object)
  • If the distance between the two objects (function above defined) is less than 65, then
    • Print the number 111 in a panel at the top (debugging)
    • Activate the mine
    • Without this line, mine wouldn't pulse correctly.
    • End the loop
    • End of distance comparison
  • End of loop
• End of function

Please note that it is not needed to include ; after }
