Re: Autowaypointing... -
09-09-2008
I put a rather complex auto waypoint generation into my RCBot that uses humans to generate waypoints automatically for use with HPB Bot type waypoints.
What I usually do is keep track of 5 last positions a player has been in (seperated by a little time) and whenever the current point is not visible fromn the last placed waypoint, a new waypoint is placed on the nearest visible point. This is for corner waypointing. There is also the distance taken into consideration, i.e. whether a waypoint already exists at the location wher you want to make a new waypoint, you don't want to make new waypoints in the sample place all the time.
There are also other special cases such as ladders (which I tried to autowaypoint) and also jumping. for example, when jumping a JUMP waypoint is placed if none are around and then a new waypoint is generated when the player hits the ground, and a path is automatically formed from the jump waypoint to the ground waypoint.
I have all the code here if any one can understand it! 
Code:
if ( IsAutoWaypointOn() )
{
if ( !m_bSetUpAutoWaypoint || !EntityIsAlive(m_pPlayer) )
{
int i;
int start = 0;
if ( EntityIsAlive(m_pPlayer) )
start = 1; // grab one location
m_fLastAutoWaypointCheckTime = gpGlobals->time + gBotGlobals.m_fAutoWaypointCheckTime;
if ( EntityIsAlive(m_pPlayer) )
m_vLastAutoWaypointCheckPos[0].SetVector(m_pPlayer->v.origin);
for ( i = start; i < MAX_STORED_AUTOWAYPOINT; i++ )
{
m_vLastAutoWaypointCheckPos[i].UnSetPoint();
}
m_vLastAutoWaypointPlacePos = m_pPlayer->v.origin;
m_bSetUpAutoWaypoint = TRUE;
m_fCanPlaceJump = 0;
m_iLastButtons = 0;
m_iLastJumpWaypointIndex = -1;
m_iLastLadderWaypointIndex = -1;
m_iLastMoveType = 0;
m_fCanPlaceLadder = 0;
m_iJoinLadderWaypointIndex = -1;
}
else

bear in mind this autowaypointing is for natural-selection in particular
