TDTK v2.1 - unleashed the horde!!

Finally I think I've done enough to warrant a release for all the new stuff I added in. It's now being uploaded to AssetStore and awaiting approval. To be honest, there are still plenty of cool and interesting stuff I really like to try. For instance, general tech tree, branching upgrade for towers, etc.. But I'm afraid that could mean another few years of waiting time before release.

Anyhow, there's a bunch new additions in this update. Here's the full list:

addition

• Added component which allows UnitCreep to attack tower or buff nearby creeps.
• Various behaviour can be set for attacking creep such as range/melee, stop-while-attack or else, etc.
• new targeting configurable parameters for tower which uses direct targeting.
• The new tower targeting option include area(all-around, fov, straightline) and priority(nearest, toughest, weakest, random). New range indicator support has been added for new added targeting area.
• Added shield for both tower and unit, which can be regenerated over time. Overlay support included.
• support tower/creep can now 'heal' damaged tower/creep.
• added new rotation mechanism to TurretTower where turret turn in y-axis while barrel turn in x-axis.
• change camera zoom-limit limitation and y-axis positioning clamp.
• add option to enable/disable tile/selection indicator.
• UI.cs now no longer use GameMessage.cs, and thus the appearance of game-message can be configure via GUISkin.
• tower base now support fire animation.
• Path.cs has not been change to PathTD.cs.
• Added new example scene and prefabs.
• Major overhaul on Documentation. Thanks for Lance.M.

bug fix

• fix bug where tower cant be build on active path on platform when path-smoothing is disable.
• fix bug where spawnEditor reset SpawnMode back to continuous.
• fix bug where projectile trajectory's angle doesn't calculate properly with respect to distance.
• fix bug where overlay is not displayed properly when the parent unit scale is not set to 0.5.
• fix bug where platform size will not be correctly auto-adjust when placed as child object where parent scale is not (1, 1, 1).
• fix bug where creep spawned by destroyed creep resetting the path instead of follow it through, again.

Here's the new updated web demo. There's a plant vs zombie ripped off there. :)

On a serious note, there's a lot of novel element, or rather not quite established element in this version. At least in term of tower defence such as creep to tower attack. So I expect it wont be as well thought out as those features in previous version. Also I'm expecting unforeseen bugs with all those new addition. I apologize for any short-sighted implementation in this update. With that said, any comment and feedback to welcomed. I'll try my best to iron out the rough edges in future updates.
