8. The
ComputeDebugPath()
method iterates over the waypoints array be-
fore the game starts and fills in the
lineRenderer
component on the
NPC. The
lineRenderer
component is then used to display the path if the
showPath
flag is set.
1. Before the method starts, it caches the playback mode and playback
type that the user sets in the editor. We do this so that the system can
set
playbackMode
to
ComputePath
while the
debugPath
is calcu-
lated:
// store settings
ePlaybackMode pbm =
this.playbackMode;
ePlaybackType pbt = this.type;
2. We then loop over a preset number of samples in the
lineRen-
derer
component, sampling the
splinePath
and storing these
samples in the
debugPath
:
SetPlaybackMode(splineMgr.ePlaybackMode.computingDebugPath);
for (int i = 0 ; i < 1024; i++)
{
Vector3 p = getPointOnCurve();
debugPath.SetPosition(i, p);
if (IsFinished() == true)
{
debugPath.SetVertexCount(i-1);
break;
}
}
3. Once the path is calculated and the
lineRenderer
component
is filled with values of line segments (from the
de-
bugPath.SetPosition()
call earlier), we restore
playbackMode
and
playbacktype
from the user:
