Damn, sorry DevliN - hadn't seen this thread for ages and totally forgot about it. I was under the impression it was only Ahli who was doing an SC2 map...
Got some catching up to do from when I last read the thread, but basically, I'm available to help you with anything data editor related. Ahli's diablo map is essentially a triggered-led combat system and he knows what he's doing so I'm not much use other than testing
...
I'd definitely suggest going for a custom user interface. My pshop skills suck, but SC2 players will know what A, S, M, H, right click, left click do. You could vastly simplify the UI to remove the command card and entire bottom 'bar'. Moving the unit wireframe to the left hand side where the minimap is, and relocating the minimap to top-right or top-left allows you to combine your custom health display near to the wireframe which always looks cool. You could then display the (five?) abilities along the bottom left of the map with their corresponding hot-key over them, and maybe with 'cooldown' bars, protruding up from them. The bars reduce as the ability cooldown reduces - no bars = ability is good to go. You are acquainted with Helrals tutorials on SC2Layout files, it's been a while since i've touched them but if you want to delegate tasks
...
(I can create test maps to better explain how this will work / look)
On to individual problems:
Railgun [REDONE] Need to find a suitable model to use that shows a ton of bullets being fired in the area. Otherwise, the rest of this ability is done.
Hero Raynors' Snipe actor, duplicated about 20 times with minor offsets will create a flurry of bullets / railgun type effect. [Data editor]
Bull Rush [REDONE] Need to figure out how to do this without the use of Triggers. Right now it increases speed and moves the unit to the target unit via Triggers.
Might be over simplifying matters, but Zealot Charge comes to mind. Unless you mean this ability applies a passive speed buff to caster, and 'blinks' to the target unit? In which case you need a:
Effect - Target (copied from blink)
Triggering a 'Set' containing the 'Apply Behaviour' (speed buff on self)
as well as the actual original Blink effect (to target unit).
[GLITCH] The "jump" is not smooth, and sometimes the landing looks like it goes on longer than it should.
Hmm, are you triggering this one? You can create a shit hot leap ability using a Launch Missile effect with a parabolic mover (akin to the Infested Terran Egg spawning that an infestor does), using the unit actor as the actual projectile actor. You can further make it more shit hot by including transfer behaviours which cause incoming missiles/effects to follow the missile-actor-projectile as it flies, allowing the jumping unit to take damage mid-air, otherwise it works as a nice 'dodge' ability to avoid incoming damage since it launches instantly.
Also:
Certain things, like Cloak and Smoke Screen, I've been putting off as they are incredibly simple to create and not as time-consuming as some of the others.
Tut tut tut tut... Get them done and out the way > feel immensely awesome for making a lot of progress on your map. That's my map-making rule 101.
Anyways, back to reading the last 4 pages in more detail.
None.
