Need some help with finding appropriate squares

[bslinger]

Hey there,

I'm trying to write the AI for a creature that will hide in the darkness, so my first step is to find the closest cell that is dark. So far I've written it using GenRadial to just search a radius, which works OK, but I'd prefer to use the new Region system if possible to get better paths. Unfortunately there only seems to be a way to search for Things in a square using that system, but not other aspects of a cell.

The other issue I have is that I would prefer to find a path that doesn't require going through a closed door - this is supposed to be an escape mechanism, and if the creature needs to fight it's way through a door it will take too long.

Here is my code so far, any help would be greatly appreciated!

class JobGiver_FindDarkness : ThinkNode_JobGiver
    {
        protected override Job TryGiveTerminalJob(Pawn pawn)
        {
            // find closest point that is dark
            foreach (IntVec3 current in GenRadial.RadialPatternInRadius(20))
            {
                IntVec3 testPos = pawn.Position + current;
                Log.Message("Looking for darkness at   " + current.ToString());
                if (Find.GlowGrid.PsychGlowAt(testPos) == PsychGlow.Dark)
                {
                    if (testPos.Standable() && pawn.CanReach(testPos, PathMode.OnSquare))
                    {
                        Log.Message("Found darkness at : " + current.ToString());
                        return new Job(JobDefOf.Goto, new TargetPack(testPos))
                        {
                            moveSpeed = MoveSpeed.Walk
                        };
                    }
                }
            }
            return null;
        }
    }

Another question: is there a way to conditionally make a Pawn render transparent or invisible? I've been trying to figure out the drawing routines but I can't get access to everything through ILSpy and I'm not familiar enough with the Unity Engine to fully understand how its Material class works.

You can change his texture to blank one.

Is there a simple way to just change the texture of a pawn? I couldn't seem to figure it out without having to deal with multiple overlaying meshes, etc.

I use

Code Select Expand


this.cleanMat = MaterialPool.MatFrom("Things/Building/2x1TableClean", true);
this.clutterMat = MaterialPool.MatFrom("Things/Building/2x1Table", true);



public override Material DrawMat
{
get
{
return (!this.TClean) ? this.clutterMat : this.cleanMat;
}
}

To change the texture of a object, not sure if this work on pawns thrugh didnt play with them
