You can find an example in the Clicker.cs script. Basically you first instantiate the building, then you call <code>SetNodes (false,myBuilding.colldider.bounds,true);// (walkable, Bounds, fullPhysicsCheck) </code> I think that's the syntax anyway...don't remember... check the Clicker.cs script. If you use fullPhysicsCheck then it will look exactly as if the building was there since the beginning. if you don't use fullPhysicsCheck the script will just use some approximations instead of the real world data.

You can fix the problem by including the AstarData.cs script from the GridData folder in the example project (2.8beta) (I should have put it in the /pathfinding folder, but well, that's why you have betas) and the AstarDataEditor.cs script from the Editor folder. The AstarData.asset asset isn't needed for the project to work. Hi Adam

From what I can understand, your scene is laid out flat and I guess the grid offset in the A* settings is set to 0 on the Y axis. Try to change the Y offset to -0.1 (just so the grid's bound's bottom isn't exactly in line with the ground), it's probably floating point errors which causes the problem (just because your goblin seems to be placed on Y position 0 it could be -0.0001 which would cause the IsPositonInsideBounds check to fail). PS: The thing with the goblins getting stuck at corners, try checking the toggle Don't Cut Corners in the A* Settings, hopefully it will help. Hope it helps, Aron Hi Raihje

Like he couldn't not stray from the grid the way the level is designed. It's just weird. I need to solve it because the cube sits there stupidly, while I walk all around. In the Debug it looks like he's just frozen with a rapid fire blue line (raycast?) in front of him. Friggen annoying. So close to having everything perfect, and something small like this tears the whole game apart. Goblin friends can't follow you, if 1 cube can't even follow you.

I only have one last small issue. If you have 1 one. make him go to one side, then ask him to go to the other side, he stands there with a blue line going right to the other side of the wall. I tried cutting in half the grid radius thing, and the height, didn't do anything. is there any way I can reduce his.. LOS to only see a square in front of him? He can go around corners pretty good for the most part, the blue line kinda has to drag him a bit sometimes but that's fine as far as I'm concerned. But I don't want the character to double back along a wall and have the AI get stuck because he's only on the other side of a wall - still unreachable though.

That seems to be the only issue now. Realized "Animation" and stuff was in the other folder lol - Fail.. Alright. So, any pointers or help, would be dually nice..

But, I put the AIFollow.cs script (I use JS, not cs, so I have no idea what it's doing really >->) but it says Assets/Standard Assets/Pathfinding/AIFollow.cs(20,17): error CS0246: The type or namespace name `AIAnimation' could not be found. Are you missing a using directive or an assembly reference? How can I fix this? And any ideas on how I can make sure the Goblins can follow the player around the maze efficiently? (Also, traps and rotating walls, and all sorts of stuff will be in there too, so Pathfinding might be a challenge for the average goblin xD) Ok, so everything in the demo worked fine, but I’m trying to make a maze, and you go

Do you set the mask to a value, and then it get's reset, is that what happens? (remember that selected layers are shown by an "O" to the left of the layer name, unity hasn't made real layerMask fields possible to do in editorGUI). And if it crashes, what do you do right before it crashes? (are you using windows or mac?). Also make sure you have multithreading disabled. <em>Sorry for answering late, I have been (and am) on holiday, but I’m home for one day so I will try to answer as many comments as possible.</em> Huh, I haven’t heard of that before.
