[Trigger] Key movement - strafe system

[Legal_Ease]

So as some of you know, I have a helicopter map. I am in the market for a trigger that allows you to move side to side while facing forward. This needs to happen while moving. Currently I can make it move side to side but the forward motion stops. My guess is that there is already a system that does this but my searches have come up empty. + rep to anyone who can find a system or write one that will permit this strafing movement.

I think I'd be able to do it, but I have no WE here...
You can use boolean[] variables when you press (?) key and set that boolean[] to true, and when releases it set it to false. Have another periodic trigger that will move your unit if the boolean[] is true. Something like that, it might not be smooth but that's how I imagine doing it.

Use arrays if it has to be MPI

 

[Malhorne]

Ah ok i understand what you wan with this^
Do what he said above but i think you will also need to set the unit facing each time.

 

[BloodDrunk]

Oh, and use SetUnitX/Y so you don't interrupt the orders.

 

[Malhorne]

Yes x)
But does SetUnitX/Y change the facing ?
I don't think so you just have to move them

 

[BloodDrunk]

Oh yeah, reminded me.

You could do exactly the same for the facing. Create 2 more booleans[] and (for example I press: A or D, set facing to ''curent facing + 2'' or something like that) do exactly the same like above.

 

[Malhorne]

Ah why not
If he wants to face the same point as use this.

Ya, I know how to do this, I already have a camera and lift system that work on this principle. But, its the "move" command that is problematic.

Here we go, this looks better

Exactly!

I was hoping someone would write it out for me or point me to a system that already exists that uses this technique so that I can just copy it rather than spending another week of trial and error before I get it right. There's a lot going on in this flight system I'm making and this is a tricky one, but I feel like some one has done it before and that would help save me a bunch of time.

+rep all around!

 

[Malhorne]

Glad you find something

 

[BloodDrunk]

Good, everything works now?

 

[Malhorne]

I think he starts to make it and we will have to wait a bit ^^

 

[BloodDrunk]

ah k then.

 

[Legal_Ease]

No nothing works yet, but since no one found a link for me or wrote something, I'm going to try it out myself. I'll try to post something tonight whether it works or not. If something is solved I like to post the result because it might help someone else.

Ok, this is starting to feel right, but it goes into a tailspin if you hold an arrow and move at the same time.

 

[BloodDrunk]

This leaks you know.

Can you post full triggers?

 

[Malhorne]

Ya this leaks on the offset position and you don't remove location at the end.

 

[FUJI]

Anyway, Where you set the udg_Chopper[1] it will not move if didn't set it or declare?

 

[Malhorne]

He post only the move trigger.
Oh set the loop to 0.03

 

[FUJI]

So it will needed to show a executing and looping trigger to solve his problem.

 

[Malhorne]

What are you saying ?
He is doing the job he is not saying he got a bug

 

[FUJI]

Hmmmm...... I see I thought there was a bug ^^.

 

[Malhorne]

No problem dude

Hahahaha, you guys are funny. But, look, you are all actually helping me quite a bit. Even though I did most of this on my own, the hints here and there and the collective knowledge keep me going. So thank you, I have more rep for you once I spread some around a bit. And I know what leaks, thanks, I don't need help with leaks. Once I get a working trigger I will be sure to clean it. For now I need to stop the chopper from spinning around in circles as it approaches it "move" destination when holding the "right arrow." See the facing angle sticks as what it was when its first held down [>] right arrow and as you approach the place you clicked on the map, the chopper breaks into a tailspin. Test Map - Choplifter 3D

integer arrow key Rotate Left Events Player - Player 1 (Red) Presses the Left Arrow key Conditions Actions Set Left[1] = 1 Rotate Right off Events Player - Player 1 (Red) Releases the Right Arrow key Conditions Actions Set Right[1] = 0

As you can see left is an integer variable which turns to one when pressed and 0 when released.

Set Chopper Variable Set cam Events Player - Player 1 (Red) Selects a unit Conditions Actions If (All Conditions are True) then do (Then Actions) else do (Else Actions) If - Conditions (Unit-type of (Triggering unit)) Equal to |cff0066ccApache|r Then - Actions Set Chopper[1] = (Triggering unit) Animation - Change Chopper[1]'s animation speed to 300.00% of its original speed Wait 6.00 seconds Trigger - Turn on Third Person Camera <gen> Else - Actions Lift trigger just FYI lift action Events Time - Every 0.01 seconds of game time Conditions Actions Set CLoc = (Position of Chopper[1]) Custom script: set udg_Real = GetLocationZ(udg_CLoc) Destructible - Pick every destructible within 60.00 of CLoc and do (Actions) Loop - Actions Custom script: set udg_Real2 = GetDestructableOccluderHeight(udg_Dest) Set TempHeight = (Real + Real2) Animation - Change Chopper[1] flying height to ((Real(Height[1])) - TempHeight) at 0.00 Custom script: call RemoveLocation ( udg_CLoc )

Here's where I set the game cam and the unit variable for the chopper. I also included part of the lift system just for fun. It uses the up and down arrows with integer variables just like left and right.

sideways motion right Turn Right Events Time - Every 0.01 seconds of game time Conditions Right[1] Equal to 1 Actions Set MoveRight = ((Position of Chopper[1]) offset by 2.00 towards ((Facing of Chopper[1]) - 90.00) degrees) Set RealX = (X of MoveRight) Set RealY = (Y of MoveRight) Custom script: call SetUnitY(udg_Chopper[1], udg_RealY) Custom script: call SetUnitX(udg_Chopper[1], udg_RealX)

This is the final motion trigger the way it is now. Somehow it needs to update the facing angle to keep it face the destination if the chopper is issued the order "move" while the right arrow is being pressed. Otherwise as it move it starts to veer off and then spins before reaching its destination. I know one solution might be to create a non GUI movement system entirely, but I'm not that bold.

 

[Malhorne]

OK dude glad you manage to do this

 

[Legal_Ease]

Well, someone suggested SetUnitX, But I think it was Doomlord on my last trigger question. Either way, this is not solved.

Someone asked me to post all the triggers, so I posted more and the test map.

I now have a sideways motion but it does not work with other commands like "move" and "attack." The purpose of the helicopter move system is to be able to do both at once. So move sideways while attacking or while moving forward. Currently, the chopper spins out of control when you try to move forward and to the side at the same time.

 

[Malhorne]

If your loop is with a very low time i don't think it will be able to receive orders normally

 

[Legal_Ease]

Hmmm, problem with that is that a higher loop time will make the motion jerky. I'll try .05 though and see if it helps.

[edit]

New Trigger Movement

Turn Left Events Time - Every 0.05 seconds of game time Conditions Left[1] Equal to 1 Actions Set MoveRight = ((Position of Chopper[1]) offset by 7.00 towards ((Facing of Chopper[1]) + 90.00) degrees) Set RealX = (X of MoveRight) Set RealY = (Y of MoveRight) Unit - Make Chopper[1] face (Target point of issued order) over 0.01 seconds Custom script: call SetUnitY(udg_Chopper[1], udg_RealY) Custom script: call SetUnitX(udg_Chopper[1], udg_RealX)

This fails. The only effect it has is to reduce the occurrences of the sideways motion which does avoid a tailspin but only by making it really jerk and slow. This makes it so that the motion isn't smooth enough to take it into a complete circle but it still starts to spin that way, it just doesn't make it into a full spin. I tried both with and without the facing angle adjustment added.

 

[Malhorne]

Tried 0.03 ?

 

[Legal_Ease]

ya, that too. I even tried .10

 

[Malhorne]

That's weird :/
You cannot give order that's the problem ?

 

[Legal_Ease]

No, the order works fine. But since the facing angle changes as the unit moves, the move-sideways command pushes the chopper offline and if you hold the key down, it will cause the unit to spin 360 before it reaches the move-destination. Try the test map, if you can't picture it. Its actually kinda funny.

 

[Malhorne]

Ahah i wanna see this x) !
But tomorrow thhis evening don't have the time.

Cool, I'm done for the night too. Hopefully you'll have an idea for a solution tomorrow. The link is posted above. ^^

 

[FUJI]

Anyway My suggestion is not to use waits, because that is a long wait time try to use counters.

 

[Legal_Ease]

Anyway My suggestion is not to use waits, because that is a long wait time try to use counters.

Waits have nothing to do with the problem. I know waits are inaccurate, I know what leaks are, I know how to use counters and I know how to clean leaks. That "wait" is there for part of the intro sequence and has nothing to do with this issue. I don't need help with that. I have a specific problem. I need a specific solution.

The question is this -

What set of triggers will allow and unit to move side to side without interrupting orders and while keeping a forward facing orientation?

The SetUnitx,y almost works except the problem as noted at length above. Please see if you can answer this. +rep to you just for checking back in though. I appreciate that.

 

[Malhorne]

I'll try to check this evening i can just simple hint/help for now.

EDIT : I'm sorry i don't understand what's the problem :S

 

[Legal_Ease]

If player holds an arrow key (see trigger above) the chopper moves sideways while facing forward. This is good. BUT! When the player holds the arrow key and clicks the terrain - giving a "move" order - while holding the arrow key the chopper starts to stray from its path and then starts spinning in circles. Not good

This is happening because the setunit order places the triggering unit left or right 90 degrees from the current facing angle. But this changes as the chopper "moves" and as it approaches the chopper moves to the side and as the chopper moves to the side it moves away from its destination 90 degrees to the side. This causes it to spin around the destination point right before it actually makes it there. I can slow the side-to-side movement speed which reduces the effect but it still strays as it moves and it looks funny. Did you fly it in the test map?

Picture the long green line as the distance to the target destination at the start.

Then see the line to the side. This is the side-ways motion from using the arrow key.

As the unit approaches the center, it starts to spin around it.

And what happens looks more like this.

 

[Malhorne]

Ok i understand what is the problem...
The way to maybe counter is to disable the strafe while moving ?
Like making a condition if it is moving ?
It is just an idea from the wake up and i will see further this afternoon.

 

[Legal_Ease]

X = STARTING LOCATION
1st Move Order Standard in game player order.
Arrow Key Movement Trigger order as written above ^
NEW TRIGGER ORDER (JASS?) Please help!
New Flight Path If this works then the flight will not look funny and there will be no spinning.

Any thoughts on how to order this to happen?
GetOrderLoc?
