Arrow Key Movement / Camera System

[OneEight7even]

this has been done before but i didnt really like any of the others ons so i made one myself.

Arrow Key Movement

1.0
1) Create 3 Variables , named "Up", "Right" , "Left". Make those 3 boolean arrays for the type and make a new variable called Players_Hero with type Unit Array. and another variable named TempPoint and its type point array.

2) Create a map init trigger and set some unit into the Players_Hero variable

3) Create a new trigger named "Up Pressed"

4) add this event to the trigger : Player - Player 1 (Red) Presses the Up Arrow key

5) add the variable up in the actions part and make it look like this
Set Up[(Player number of (Triggering player))] = True

6) Make that for all the arrow keys exept for down.
Example:

SPOILER

]Up Press

Events

Player - Player 1 (Red) Presses the Up Arrow key
Player - Player 2 (Blue) Presses the Up Arrow key
Player - Player 3 (Teal) Presses the Up Arrow key
Player - Player 4 (Purple) Presses the Up Arrow key

Conditions
Actions

Set Up[(Player number of (Triggering player))] = True

Right Press

Events

Player - Player 1 (Red) Presses the Right Arrow key
Player - Player 2 (Blue) Presses the Right Arrow key
Player - Player 3 (Teal) Presses the Right Arrow key

Conditions
Actions

Set Right[(Player number of (Triggering player))] = True

Left Press

Events

Player - Player 1 (Red) Presses the Left Arrow key
Player - Player 2 (Blue) Presses the Left Arrow key
Player - Player 3 (Teal) Presses the Left Arrow key
Player - Player 4 (Purple) Presses the Left Arrow key

Conditions
Actions

Set Left[(Player number of (Triggering player))] = True

1.1
Now we are going to create the "release triggers" you will basicly be doing the same thing as the pressed ones but like this

Up Release

Events

Player - Player 1 (Red) Releases the Up Arrow key
Player - Player 2 (Blue) Releases the Up Arrow key
Player - Player 3 (Teal) Releases the Up Arrow key
Player - Player 4 (Purple) Releases the Up Arrow key

Conditions
Actions

Set Up[(Player number of (Triggering player))] = False
Unit - Order PlayersHero[(Player number of (Triggering player))] to Stop

Now do that for all the arrow keys. exept dont add the Unit - Order Stop action in any of the other ones.

2.0
Create a new trigger named Movement. this trigger will be detecting the variables to order a unit to move. for example :
if the variable Up is = True then it will move that unit up.
1) create the event Time - Every 0.25 seconds of game time

2) add the action Player Group - Pick all players and do actions
Loop actions

3) in the loop actions part create an If/Then/Else action. so far it should look like this :

Untitled Trigger 001

Events

Time - Every 0.25 seconds of game time

Conditions
Actions

Player Group - Pick every player in (All players) and do (Actions)

Loop - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions
Then - Actions
Else - Actions

in the If - Conditions part of the trigger add these conditions

Up[(Player number of (Picked player))] Equal to True
Left[(Player number of (Picked player))] Equal to False
Right[(Player number of (Picked player))] Equal to False

.

4) after that , create under the Then -Actions part the variable TempPoint like this

Set TempPoint[(Player number of (Picked player))] = (Position of PlayersHero[(Player number of (Picked player))])

after that action were going to add the moving part of it it should look like this

Unit - Order PlayersHero[(Player number of (Picked player))] to Move To (TempPoint[(Player number of (Picked player))] offset by 90.00 towards (Facing of PlayersHero[(Player number of (Picked player))]) degrees)

Now do the same thing in more loops for all the variables. it should look like this at the end :

SPOILER

Movement

Events

Time - Every 0.25 seconds of game time

Conditions
Actions

Player Group - Pick every player in (All players) and do (Actions)

Loop - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Up[(Player number of (Picked player))] Equal to True
Left[(Player number of (Picked player))] Equal to False
Right[(Player number of (Picked player))] Equal to False

Then - Actions

Set TempPoint[(Player number of (Picked player))] = (Position of PlayersHero[(Player number of (Picked player))])
Unit - Order PlayersHero[(Player number of (Picked player))] to Move To (TempPoint[(Player number of (Picked player))] offset by 90.00 towards (Facing of PlayersHero[(Player number of (Picked player))]) degrees)

Else - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Right[(Player number of (Picked player))] Equal to True

Then - Actions

Set TempPoint[(Player number of (Picked player))] = (Position of PlayersHero[(Player number of (Picked player))])
Unit - Order PlayersHero[(Player number of (Picked player))] to Move To (TempPoint[(Player number of (Picked player))] offset by 90.00 towards ((Facing of PlayersHero[(Player number of (Picked player))]) + -90.00) degrees)

Else - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Left[(Player number of (Picked player))] Equal to True

Then - Actions

Set TempPoint[(Player number of (Picked player))] = (Position of PlayersHero[(Player number of (Picked player))])
Unit - Order PlayersHero[(Player number of (Picked player))] to Move To (TempPoint[(Player number of (Picked player))] offset by 90.00 towards ((Facing of PlayersHero[(Player number of (Picked player))]) + 90.00) degrees)

Else - Actions

You're still not done. now for the diaganol movement part. we wont be actually ordering the unit to move diaganol we will move him instantly to point. this is pretty simple so im just going to post the trigger for diaganols.

Stop Turn

Events

Time - Every 0.30 seconds of game time

Conditions
Actions

Player Group - Pick every player in (All players) and do (Actions)

Loop - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Up[(Player number of (Picked player))] Equal to True
Left[(Player number of (Picked player))] Equal to True

Then - Actions

Unit - Make PlayersHero[(Player number of (Picked player))] face ((Facing of PlayersHero[(Player number of (Picked player))]) + 65.00) over 0.10 seconds
Set TempPoint[(Player number of (Picked player))] = ((Position of PlayersHero[(Player number of (Picked player))]) offset by 10.00 towards (Facing of PlayersHero[(Player number of (Picked player))]) degrees)
Unit - Move PlayersHero[(Player number of (Picked player))] instantly to TempPoint[(Player number of (Picked player))]
Animation - Play PlayersHero[(Player number of (Picked player))]'s walk animation

Else - Actions

If (All Conditions are True) then do (Then Actions) else do (Else Actions)

If - Conditions

Up[(Player number of (Picked player))] Equal to True
Right[(Player number of (Picked player))] Equal to True

Then - Actions

Unit - Make PlayersHero[(Player number of (Picked player))] face ((Facing of PlayersHero[(Player number of (Picked player))]) + -65.00) over 0.10 seconds
Set TempPoint[(Player number of (Picked player))] = ((Position of PlayersHero[(Player number of (Picked player))]) offset by -10.00 towards (Facing of PlayersHero[(Player number of (Picked player))]) degrees)
Unit - Move PlayersHero[(Player number of (Picked player))] instantly to TempPoint[(Player number of (Picked player))]
Animation - Play PlayersHero[(Player number of (Picked player))]'s walk animation

Else - Actions

There you go you made an arrow key movement system. in case you didnt understand it or i didnt explain well take a look at the triggers your self in the demo map (Camera system is in demo map also). im pretty sure i spelled alot of things wrong so dont tell me about it. idk if im good or not at explaining things either soooo

Good Tutorial but it'd probably be better with some pictures here and there.

I suggest replacing the [code] tags with [trigger] tags, which are specifically built for GUI.

For the spoilers, you could use [hidden=Spoiler](content)[/hidden], which would produce:

Spoiler

(content)

Also, Unit - Move Unit (Instantly) resets animations as far as I know, so that would look a little jumpy.

[SoCal_420]

nice system i could use it.

[Kieve]

Is [that] how button (hold) functions work? Hm. Need the pair of Press and Release event triggers.
Seems so obvious, and yet it never occurred to me before. Wonderful.
Not too keen on the rest of the code, but that's personal preference - easy to understand at least.

[Need_O2]

would be better with JASS
hey dont look at me like that Im a Lamer
My job is causing annoying situations

Ups including much leaks too

[CombatTheWombat]

hmmmm, dont use jass for anything you can do in gui, as the saying goes, "don't fix what isn't broken"

[PurplePoot]

hmmmm, dont use jass for anything you can do in gui, as the saying goes, "don't fix what isn't broken"

That's absolutely not true, but on the other hand, some people use GUI too, so GUI tuts are useful too...

[Wolverabid]

Map makers should find this tutorial helpful and useful.

Nice tut, I'm going to use this in my RPG.

But GUI is leaktastic!

Thank you for the tutorial. It helped me make my Role-playing a little nice. 5/5

[Kidd|WhiteHeaven|]

Great and usefull. Especially for dodgeball type games.
Note: FPS view cameras really are hard.

[Pandarian-Warrior]

dude...i just learned how to make an arrow-key movement system.
thank you, thank you very much

[Bill_14]

my opinion is do not try to make such a system

i made one for my rpg map, and the unit is walking awfully, it is like right clicking 4 times a seconds in front of the unit. Also if there is an obstacle in front of the unit, it won't go str8.

it's good however to show to people how to do this, even for practice, good work
