This bundle is marked as approved. It works and satisfies the submission rules.
Knockback 2D will knock a unit back - without interrupting orders - while also considering pathing checks for different collision sizes. It destroys trees and/or debris without destroying bridges and the user can fully configure it. It allows for deep-water movement if desired.
You specify the speed of the knockback indirectly by giving it a distance to travel and a time to travel it within. This uses the same formula as Berb's Knockback Lite.
If the unit hits impassible terrain, it will "bounce" in a form of a geometric deflection angle. This can be toggled on or off per knockback.
The demo map features a template where you can add on-loop behavior. To the knockback.
It is in GUI, meaning it is World Editor friendly. I hope that it is also easy to understand how it works as the variables are pretty straightforward:
- A unit to knock back (Knockback2DUnit), an angle (in degrees) to knock it back (Knockback2DAngle), a distance it will travel (Knockback2DDistance) and a length of time to complete the travel within (Knockback2DTime).

How to install
- Copy the Unit Indexer and Knockback 2D triggers into your map.
- There is one dummy created in the Config trigger that is a simple Undead Ghoul. It could just as well be a Peasant or Peon. Just make sure that the unit type created has the harvest ability and doesn't have some passive effects like Phoenix fire or immolation.

-------- Robust Pathing at 0 is only safe for collision sizes 16 and lower, but requires only one SetItemPosition check per timeout. --------

-------- -------- 1 checks collision vertically and horizontally to momentum. Uses an extra 4 SetItemPosition checks pet timeout. --------

-------- -------- 2 checks collision diagonally with momentum. Uses a total of 9 SetItemPosition checks per timeout. --------
-
-------- In any case, if the unit only has size 16 or lower collision, only one SetItemPosition check will be used for it. --------
-
-------- If RobustPathing is set to 2 and the unit has 36 or less collision, it will only use the normal check of 5 SetItemPosition calls --------

Changelog
- 1.0.0.0 - Release
- 1.0.0.1 - Changed IssuePointOrder to IssuePointOrderById.
Now uses 1 trigger instead of 2. - 1.1.0.0 - Added a "bounce" functionality to the knockback.
Made an add-on to support knocking back adjecent units (collateral knockback) - 1.2.0.0 - Added an additional flavor, "Knockback2DPause", which can be set only during map initialization. I also added a SetUnitPropWindow for when units are not paused, so that they appear motionless aside from the knockback.
- 2.0.0.0 - Added five new, optional variables: height, pause, bounce, kill trees and an on-impact trigger. I will elaborate more on what these do in a future post.
- 2.0.1.0 - Added a Gravity configurable that determines how quickly the unit will descend after it reaches its peak.
- 2.0.2.0 - Gravity can now be configured per-knockback
- 2.1.0.0 - You can now specify looping FX strings per-knockback. Changed the addons to custom script as they were mostly custom script anyway.
- 3.0.0.0 - Split the one monolithic trigger into four smaller and more manageable ones. Units will no longer potentially pass through buildings if they had a collision size greater than 16.
- 3.1.0.0 - Updated the Knockback 2D and Knockback 2D System triggers to add an option "Knockback2DSimple". When this boolean is true, all normal pathing is ignored except to make sure the unit is within the world bounds.
- 4.0.0.0 - Everything has been overhauled.
- No custom object editor data is used. Inferno was really only useful on my demo map, but it had issues like ignoring structures, pathing blockers and actually not considering collision sizes. That's right, despite that I had all the object data set properly to make it recognize various collision sizes, it was not doing that. Also, the custom Flame Strike ability had a delay on it which I could not get rid of no matter what I did. The ability could be cast at most per 0.02 seconds, and when you set its Object Editor duration to 0.00 instead of 0.01, the game crashes.
- Real collision is used now.
Code (Text):
//Each [ ] represents a SetItemPosition call on that space
//Collision when pathing robustness is set to 0 or the unit's collision size is
//set to 16 is simply one SetItemPosition call.
//With robustness set to 1 or the unit has 32 collision:
[ ]
[ ][ ][ ]
[ ]
//With robustness set to 2 and the unit has 48 collision:
[ ]
[ ] [ ]
[ ] [ ] [ ]
[ ] [ ]
[ ]
//At 64 collision, the white spaces just become more pronounced.
//As you can see, knocking back a unit with more than 32 collision size and
//robustness set to 2 requires quite a few SetItemPosition calls. I am not using
//SetUnitPosition with a dummy due to potential "enter/leave region" events in a
//user's map.
- The friction can now be customized per-knockback. I also fixed the default friction as I had improperly copied Berb's formula used in Knockback Lite - that problem is fixed now.
- There is a dummy harvest unit created to sample if a destructable is debris or a tree (the user can change the issued order from attack to harvest if they only want to kill trees).
- The Knockback 2D System trigger has been converted into optimized JASS so I could make the system run more smoothly.
- The two addons have been merged into the Knockback2D System JASS script.
- You can configure the rate at which special effects spawn under a unit being knocked back.
- 4.1.0.0 - After being notified by Arad MNK that distance wasn't working properly, I found a pretty serious thing I've neglected the whole time this resource has been around. The friction I had been using was nearly 0 because I didn't copy Berb's formula properly, so the unit wasn't visibly slowing down. Therefore, the unit was always going too far. This update corrects that issue. You can change the friction to 0 to go back to the way it was before.
- 4.2.0.0 - Friction can now be customized between 0 and 1 without adverse effects. Greatly improved the fluidity of secondary knockbacks by averaging the angle, distance and time of the new knockback with those of the first. A new option, Knockback2DUnbiasedCollision, has been added to remove alliance checking from the built-in knockback collider.
- 4.2.1.0 - Added a way to customize the destructable death radius and it can also be done per-knockback. Also added a fix so that items don't get displaced when unhidden.
- 4.2.2.0 - Flying units no longer knock back ground units and ground units no longer knock back flying units.
- 4.2.3.0 - Flying units now display special effect art attached to their "origin". Simplified the pathing check for flying units to only check for air unit pathability.
- 4.2.3.1 - Fixed an issue where Knockback2DOverride would break all subsequent attempts to knockback the unit running Knockback 2D <gen> (checking conditions) instead of ignoring them.
- 4.2.4.0 - Knockback collision now tracks Knockback2DSource
- 4.2.5.0 - Fixed an issue with large maps not working correctly. Just update the JASS script to apply this fix. The map isn't updated yet but I've updated the posted script.
