why not if(n_mapAndreas > n_Z) ?

For does not bug occur with small increases!

Problems with this
pawn Code:
MapAndreas_FindZ_For2DCoord(p_X, p_Y, p_mapAndreas);
that is called pretty early in the movie... (should be called after the height check)

Oh Yeap, thanks !! (I had not noticed haha

I'm thinking of something interesting. On putting +90-90 it create a triangle:
The invalid path is hypotenuse and the "adjacent" side will always be the new path (interestingly, it is this part, is the size of the construction ..
)
I tested a lot, it works with buildings. The problem is that if the NPC is under one roof and the player not. The NPC BUG, or stairs for example
The algorithm is correct, but there are exceptions in San Andreas. I think one way to deal with these exceptions, is to check a given area is a building.
For checking a point is a building. I think we do four points and check MapAndreas Z POS, if the same Z POS in four points. Yes, is a building
Example:
PHP код:
static
Float:4points,
i,
Float:zPoint;
for(i = 0; i != 4; i++) {
pontoX = edificioX + (5.0 * floatsin(-90.0 * i, degrees)),
pontoY = edificioY +(5.0 * floatcos(-90.0 * i, degrees));
MapAndreas_FindZ_For2DCoord(pontoX, pontoY, zPoint);
4points += zPoint;
}
if(floatround(4points) % 90 == 0) {
// 4 points have the same MapAndreas Z Pos
// x
// x x
// x
// 5 * 4 = 20 metters
}
)
