You know, when we use a building like Terran Starport and want the player to build a unit from it to choose an option ; this technique always has been restricting our choices to 5, but I've thought I've something very simple to increase it: using Rally Point, send your choice over the wanted direction and each direction (it could simply be left/right) would be an option.
So a single Wraith could give you a lot of possibilities... and there are 5 different units you can build!

I hope I've been clear and that I am not being a noob just reviving an already-known technique

The main advantage of a build system is its speed. If you make the player have to change the rally point before building to select certain options, you'll lose that speed. Having to have the unit move a pixel will also add a slight delay the system's reactions. It'll give you a lot of options, sure, but I'm not convinced that it will work better in practice than simply allowing "combos" between units (instead of between rally points and units) or using multiple buildings.

As long as you're not using it for spell casting, because then there would just be too much lag in between a player hitting 'w' and their spell starting.

The delay actually doesn't have to be very long at all. What you need to do is use a stargate and corsair since it has a fast acceleration. Then set it up like so:



The delay will be half a second, if even that. Not useful for spells since changing it will be too laborious, but still, the system isn't a bad idea.

Combos are faster. Period. The other option is to use Eud Unit Selection.

Combos don't allow you to spam spells. You'd have to wait a lip bit between spells, and some times mess up and cast another spell.
If the staport was in the very middle if the map, the player could just click onf the minimal to set the rally point, wouldn't be too hard.

There ya go!
Moreover, it wasn't intended to be used for spell-casting in my head, at start.
Anyways, it was just a thought and I do not even plan to use it yet.

It would be useful for mutliplayer RPGs, specifically for things like talking to NPCs, etc.

This is already on the wiki, on the pooly-named Selection Systems page: http://www.staredit.net/wiki/Selection_Systems

I haven't seen it ;o

Similar idea, but in my mind a little better: Why not simply have combinations of units be a possibility? Basically, you detect when the first unit is built, and start a death count that goes to 6, for example, if a second unit is built during that 6 trigger-cycle period, then a combination option is selected, otherwise the first unit is used alone. This would give 30 different combinations for the StarPort alone, and could be done entirely with hotkeys.

A good idea, but it would have a hard learning curve (not to mention the delay makes it a nono for spell casting). I mean, it wouldn't be too hard to get used to, but much more difficult than just pressing o.

Pressing o? Is that how you hotkey ralley point? 'Cuz you can also just right click

Well, the other option if you want to make it for spell casting would be to detect mineral loss, it could be much faster. Also, people don't really complain much about maps that have spellcasting systems without hypertriggers, so apparently even a 2 second delay isn't annoying enough to make people not want to play, so a half second delay shouldn't be an issue.

I'm saying o as in corsair, or any other unit hotkey.

I misread your previous post, I thought you said the delay would last six seconds, not six trigger cycles. Carry on then >.>

Isn't this already over-used by Arena maps like WaF ?

TS 1.6 is using it too.
