Post subject: Player Position Detection

I'm using mervbot and I was trying to figure out how to make it so that every time a there was a player in a square area on the map, it would start a timer. Any ideas on how to do it?

EVENT_PlayerMove
Check player's position there (p->tile.x and p->tile.y)

a very easy way is to use the playermove event in spawn.cpp

Code: Show/Hide

case EVENT_PlayerMove:
{
Player *p = (Player*)event.p[0];

if ((p->tile.x == 512) && (p->tile.y == 512))
{
sendPublic("*timer 5");
}

}

This will start the timer when a player cosses the "center" of a map.

Damn, sos was faster...

Can you make it so that a player can only send a command within a block of tiles? It seems to ignore it in a rectanle, but works on a specific tile. (both are within the player level command case in commands.cpp
work:

Code: Show/Hide

if ((p->tile.x == 512) && (p->tile.y == 512))
{
if(c->check("command")
{
sendPrivate(p,"command recieved");
}
}

No work:

Code: Show/Hide

if ( ((p->tile.x >> 510) && (p->tile.y >> 510)) && ((p->tile.x << 514) && (p->tile.y << 514)) )
{
if(c->check("command")
{
sendPrivate(p,"command recieved");
}
}

This isnt cut-and-paste, so ignore missing ";" and such junk.

This is a generic sample of code for checking if some point X, Y is inside a rectangle:

Code: Show/Hide

if (x >= X_MIN && x <= X_MAX && y >= Y_MIN && y <= Y_MAX)

Yes, yes, thank you. I got myself tripped up on == and >= and somehow i carried it over to >>.
