Hi,
What would be the best method to know where the player is? For example I would like to create a fucntion (called by the player's action) that does one thing when the player is in room 1, but does something else when he is in room 2. There is no door between the rooms so the player can freely walk from one room to the other.

Thanks for helping

use c_trace.

Okay but then I need to run c-trace periodically and have something else (entity or map entity) to respond and I thought that c-trace should be used sparingly since it is slow and takes a lot of processor time...
What do you think?

You can work with:
if (vec_dist(player.x,vector(x,y,z)) < dist)

Indeed I can use that also
Thanks both of you (Cowabanga and Widi) for the tips

Alternatively you could use "zones" ... by this I mean that you have invisible, passable blocks. When the player collides with one of them (i.e. steps into / onto them) you set a global "zone variable" to indicate which "zone" (or room) he is in.

Then your action only needs to check the "zone variable" to determine the whereabouts of the player.

This, of course, does not pinpoint the exact location of the player. It only tells you in which zone he is ... but maybe that's good enough for what you want to do ?

Cheers,
Andreas

(I used something similar with A5 to determine which torches in a dungeon needed to be "lit" when the player was near ... just so as to limit the number of active particle emitters etc.)

Andreas,
That is indeed an even better solution.
Thanks for the tip
Best regards
