Jedi-SDL / Recognizing Tiles

[jasonf]

a T-turn is really simple.
Basically, you can test to see if both left and right options are available to you and use some algorithm to choose between them.

if( testTileIsObstacle( currentAngle, currentspeed ) = false )
begin

end
else
begin


left := testTileIsObstacle( currentAngle - 90, currentspeed );
right := testTileIsObstacle( currentAngle + 90, currentspeed );

if (left and right) then
begin
   if (random(10)>5) then
   begin
      direction :=-90;
   end
   else
   begin
      direction := 90;
   end;
end;
if (left) then
begin 
   direction := -90;
end;
if (right) then
begin
   direction := -90;
end;
if(left=false and right=false) then
begin
   direction := 180;
end;
end;

something along those lines might help..
Or, if you don't want random, you can always have some controlling variable which alternates between left and right so one unit goes left the next goes right in the event of a T-Junction

This sort of logic is what Pac Man used. Only pacman included the player's location in relation to the monster to make them chase or run away.

Well, my goal is hopefully to make it so they choose the route they are most likely to survive in. I'm mostly experimenting with this game, so the more I can put in like that, the better off I will be. I'm using this game as a learning experience..

On another note, I think you guys have given me enough info for me to 'formulate' my own method of doing this, which was what I was trying to do all along All I needed was some example code

Thanks JasonF and arthurprs! If I need anymore help, I'll just post again...

Yes, thats good, but what happens when the road becomes a T-turn, and the person has 2 methods to go? that would make your method extremely complex, because it would add another entire dimension to it.

Just add "Troad" to TITLEdirection ?
