now i need to be able to rotate the circle also around Y/X direction |
wow now that's more confusing than before xd this is really difficult tho.
This can still be applied (I guess so):
On plugin_init:
PHP Code:
register_clcmd("inside_circle", "inside_circle", ADMIN_KICK);
Checking if the player is inside the circle:
PHP Code:
public inside_circle(id, level, cid)
{
if(!cmd_access(id, level, cid, 1)) return 1;
new ent = -1, target_circle = 0, Float:Circle_Origin[3], Float:Player_Origin[3], Float:wanted_distance = 250.0, Float:z;
pev(id, pev_origin, Player_Origin);
while( (ent = find_ent_by_class(ent, "health_circle")) > 0 )
{
pev(ent, pev_origin, Circle_Origin);
if( (z=get_distance_f(Player_Origin, Circle_Origin)) <= wanted_distance )
{
target_circle = ent; wanted_distance = z;
}
}
if(target_circle > 0)
{
new Float:Radius[3];
pev(target_circle, pev_fuser4, Radius[X]);
if( (floatsqroot(get_distance_f(Player_Origin, Circle_Origin))) < floatsqroot(Radius[X]) )
{
console_print(id, "Player is inside circle");
}
else
{
console_print(id, "Player is not inside circle");
}
}
else
{
console_print(id, "No health circles were found");
}
return 1;
}
Although this code searchs if the player is inside the circle, sadly it will search in a sphere. So, that is a beginning. The rest I think you can manage to do it (I hope so).
Edit: I think I know how to check it only in a circle but that would require to the circles have a rotation of 0° (or 180°) or 90° (or 270°).
After "if( (floatsqroot(get_distance_f(Player_Origin, Circle_Origin))) < floatsqroot(Radius[X]) )" we can add something like this:
PHP Code:
if( Player_Origin[Y] == Circle_Origin[Y] ) // only if the circle has a Y rotation of 0° or 180°
or...
PHP Code:
if( Player_Origin[X] == Circle_Origin[X] ) // only if the circle has a Y rotation of 90° or 270°
For the current rotations, in theory that should work.
