This is a simple, yet very effective test map. It allows a player to easily cast a projectile to a point of his/her choosing. A few people separately thought it up (including myself, Kaias, and qPirateKing), but no one ever really made the system.
How to Cast:
1) Select both wraiths (you will have to use multi-select because there is one wraith on top and one on the bottom of the map)
2) Hotkey (it'll make life easier)
3) Hold shift while ordering the unit to move to a spot
4) ???????
5) Profit!
The Concept:
The concept is centered on Starcraft's waypoint system. For those of you who don't know, the waypoint system is essentially a "to-do" list for units. When you order a unit while holding shift, it sets destinations/commands for that unit, which performs each in order. With that vital background information out of the way, let's discuss the map, shall we? The map consists of a high templar and two wraiths (ignore the burrowed units, they just save locations). When you shift+order the wraiths, two things will occur. First, since the top wraith is moving to the right when it is ordered, it will continue moving to the right (because of the waypoint system). The second wraith, however, having no previous command, immediately moves. The map detects when the bottom wraith moves, and, when it does, the top wraith (the one moving to the right) is teleported over the high templar (hero unit). Because it was teleported, its previous command (the command to the right) was canceled, and the wraith continues on towards the next destination (in this case, the point of the player's choosing). The map simply gives the wraith to a neutral player (so that the player cannot see and cannot control the wraith) and makes a simple effect.
Information on the Triggers:
For the sake of accuracy, I used inverted locations. When used properly, inverted locations are able to detect the pixel movement of a unit (ask for more information if it is necessary). I used two inverted locations: one for the wraith on the playing field (when you cast the spell) and one for the bottom wraith. I used the locations to detect when the bottom wraith moved and when the wraith on the playing field stopped.
Closing Remarks:
This was a relatively simple test map, so there are still some bugs. The main problem with the system so far is the movement of the projectile wraith. If the player shift+orders the wraith to the right of the high templar, the projectile wraith will swerve while turning around. Also, the wraith occassionally will not move to its destination (I'm pretty sure there are ways to prevent this). Anything unclear? Any questions or comments? Post in the thread.
