Urm.. Arrow key moving?

[SineCosine]

Well, this little map I'm making has 4 heroes..
One hero, in particular, is more keyboard oriented for reasons I'd rather not mention.

So, I've decided to add in an optional method of movement to whichever player picks this keyboard-oriented hero.
I want the arrow keys the player presses to move the hero.

Up - Moves the hero forward
Down - Makes the hero face backwards and move from the new 'forward'
Left - Hero does not move, only turns left
Right - Hero does not move, only turns right

Detecting which player has the hero is easy..
The rest.. uhh..
Wha-?

I can't think of how to do it as I've never done it before =x
I can't use SetUnitPosition.. can I?

Also, the RotatingCamera thing..
When I use..

RotateCamera 80Degrees
RotateCamera 40Degrees
(Note that these are not the actual Jass functions xD)

I expect the camera to move120Degrees,
However, it just turns 80 Degrees, resets and then turns 40Degrees..

How do I get around it? o.0
So..
I'm just looking to be guided in the right direction.

01) How do I make a keyboard-arrowkeys movement system?
02) How do I get around the camera rotating in this weird way?

You can try looking at something like this:

Basically, they use a global boolean array (based on the player's id, you won't really have more than one unit moving per player based on the arrows key except for in specific cases anyway).

When you do left/right, it sets the facing + (somefacingfactor) [eg: 5] or facing - (somefacingfactor) periodically.

When you have up/down, it moves the unit forward/backward (when moving backward the speed is halved or something). Basically x + (someMovementFactor) * Cos(facing*bj_DEGTORAD) and same for y except you use Sin().

For the camera rotation, just set it to the facing of the unit.

 

[SineCosine]

Nonono,
I have to set it to the ((facing of the unit - 90.00) * bj_DEGTORAD)

I tested it myself.
Anyways, I tried to make my own arrow key movement system -___-

It failed horribly.
Really really horribly =/

I feel like emo-ing =(

Try to look at Blizzard-made maps, such as Azeroth Grand Prix, hence it has WASD movement.
Blizzard made those map as open-source maps from which you could learn etc. etc. Although, it has a weird turning system, because you will have to walk in a wide half-circle to turn 180 degrees, but I'm sure there's a way to get around this issue.

 

[SineCosine]

Blizzard..
Made it's own WASD movement map.. o.0

*Rips hair out*

Anyways, I tried the system PurgeandFire linked to.
I can't get it to work ._.
The unit will only move when the camera reaches its bounds.

As in, the camera does not lock onto the unit, like it should ._.
I am confused, I couldn't implement the arrow-key system =/

*Goes to check Blizzard's system*

[EDIT]
I couldn't find out how they did it ._.

 

[Nevyll]

Try to lock the camera on the unit and proceed by calling the BJ CameraSetupApplyForPlayer :thup:

And about that Blizz map; I know, it's hard to understand, but maybe you will have to look at it more than once.

There are lots of arrow key + 3rd person cam movement systems on the web. Don't write your own unless you are really experienced with JASS.
Use them!

 

[SineCosine]

Bleh,
Then I wouldn't learn anything.

Unless it's T32.
I don't understand it, but I can't do without T32 now =x

This may help you.

Its just sad that those arrow key events are delayed as hell.. :´(

You cant really use them to any stuff that is too important for the gameplay. At least not in multiplayer maps.

 

[SineCosine]

Hmm..
I kinda' figured out how the hero facing works (the angles)
By testing.

Thing is, after I tested it, all my cinematic triggers that had TriggerSleepAction stopped functioning at all.
So, I had to remake them with timer and it was all golden ._.

I still can't use TSA, which might be a good thing, afterall lol
