[Trigger] Jumping

[GhostWolf]

I tried making a unit "jump" with the bird ability a lot of times like everyone says, but it NEVER worked.
Can someone give me a trigger that works ?

And another question, if I use harrays, does index [0] is also working ? or it starts from [1] ?

Thanks in advance.

 

[PurplePoot]

• Arrays start from [0]
• Trigger, please?

And another question, when changing unit's flight height does it interfer with the units orders ? (for example if I order a unit to move and mean while change his height, will he stop moving ?)

 

[PurplePoot]

You need to set the fly height too, GhostWolf. Not just add Crow Form.

Anyhow, no, it won't interrupt orders.

 

[Pyritie]

You just add crow form, change its flying height, then remove crow form.

All it does is allow you to change the flying height of units, not make them jump.

 

[GhostWolf]

Ah I see, because on the-helper they just put the Add/Remove crow form and didn't say anything about changing flying height.

So is the Arc the unit moves through also with triggers or is that the effect of crow form ?

 

[Pyritie]

Nope. That's all triggers.

All that crow form does is change the flying height. It does not move the unit at all.

 

[PurplePoot]

All that crow form does is change the flying height. It does not move the unit at all.

*Allow you to change the flying height of a non-flying/hover unit.

 

[Just_Spectating]

the flying height thing is also confusing, its going to be (your desired height) at (height per second)

 

[GhostWolf]

Is there a better way to make an arc "jump" instead of this ?

(Don't bother me with leaks or anything, just made this as an example )

The "at 500" thing means it changes its flying height over 500 seconds (which is far too long).

Also you need the wait.

That would be a triangle, Pyritie, no an arc.

Here's a funky function for calculation of an arc (yes, this is Triggers (GUI), but some things aren't the best done in GUI, and you can always call this with a line of 'Custom Script')

function JumpParabola takes real dist, real maxdist,real curve returns real
    local real t = (dist*2)/maxdist-1
    return (-t*t+1)*(maxdist/curve)
endfunction

Suggested use:

First, put this function in your map header, then, use this:

(using variables Real MaxDistance, Real DistanceTraveled, Real NextZHeight)

• -------- I assume that by this point in your trigger MaxDistance and DistanceTraveled have been set --------
• Custom script: set udg_NextZHeight = JumpParabola(udg_DistanceTraveled,udg_MaxDistance,1.8)
• Unit - Set (Someone)'s Fly Height to NextZHeight at 0.00

 

[GhostWolf]

Both of you are wrong

First 500 means 500/sec, so the unit's height changes to 500 in 1 second.

Second of all, it isn't a triangle since the unit continues to move.

 

[Just_Spectating]

uh, i explained that earlier when everyone was ignorant.

 

[Pyritie]

Yes, it moves in a triangle, not an arc. If the unit is moving at a constant speed then looking at its flightpath it's like an upside-down "v".

And I'm very sure that it's "Change unit's flying height to X over Y seconds".

 

[GhostWolf]

It will be a triangle only if the unit moves exacly at the height-change speed.
A slight diffrence will make it a more arc-like move.
A big diffrence will make it a normal arc.

 

[Pyritie]

Nuh-uh.

It changes its height at a constant speed. Not fast first then slowing down.

 

[GhostWolf]

What I meant is, if the end of jump is 600 from the jumping unit, the unit's speed is 300/sec, and the height is 300/sec (just an example), it will be a triangle, but if change even one of this things it will be more an arc then a triangle depends how much u change.

And if you keep not beliving just try it, because I did and facts are facts ^^

 

[Pyritie]

Oh, I've tried it alright. If the units speed is 300 and the distance between the two points is 600, then that second number field should be at 1 (each), because it'll be going up for 1 second then going down for another second, then it'll be at the end point.

 

[GhostWolf]

didn't understand your point

 

[Just_Spectating]

because if a unit has 300 ms ghost, it will take 2 seconds to reach a 600 distance

 

[GhostWolf]

Yes... point is ? so what if it moves in 2 seconds...

 

[Waldbaer]

Well, I'm not sure if you want to USE this or if you want to LEARN this.
If you want to USE it, maybe you should take a look at my Jump System.

Using this, you only have to give the unit that should jump, the target location, the desired max height of your jump and the duration of the jump and it will jump in a perfect parabola.

 

[Bob27]

Yea I recommend Waldbaer's jump system, as i've used it before and its very simple to use.

 

[Pyritie]

And it's in an arc! Unlike the flying height thingy.

 

[GhostWolf]

Its not really real since the unit seems to go down exacly at the speed he went up (correct me if im wrong).
The instant-jump is cool
You can cast it while on air and its really funny

And Pyritie, don't know what with you but I managed to make a nice arc with changing height so say whatever you want...

 

[Pyritie]

It's probably not an arc though.

 

[PurplePoot]

If you'd try JumpParabola, you'd find it is an arc. You'd also find Pyritie's way is definitely a triangle.

 

[GhostWolf]

Ok this is my last comment in this thread since it goes to no where.

Unless the units speed is "Distance_Of_Jump/2" and the height goes also "Distance_Of_Jump/2" the jump will NOT be a triangle.
I tried it and it worked perfectly.

Don't know whats your JumpParabula but there is gravity you know and if, say, a unit jumps from a cliff his speed should increase as he falls.

 

[PurplePoot]

Triangles don't have to incline at a 45 degree angle, so it is a triangle.

 

[Pyritie]

Here. Hopefully now you will get it.

 

[PurplePoot]

The arc isn't quite like that pyritie (a Parabola isn't that round), but that's the general idea.

And I didn't suggest Waldbaer's jump system, someone else did, but it is a funky system.

 

[Waldbaer]

Its not really real since the unit seems to go down exacly at the speed he went up (correct me if im wrong).

You noticed correctly, but your conclusion that this is not real is wrong. The gravitation always accelerates an object at the same amount, so if the object is rising, it will be braked as fast as it will be accelerated when it comes down again. Therefore, the speed when it's going up is exactly the same as when it comes down again (if start and target are at the same height, of course; air resistance not considered since it is negligible for jumping).

 

[GhostWolf]

Thats why I added "if the unit jumps from a cliff" but it doesn't really matter since its just warcraft lol

 

[Waldbaer]

In this case, your eye is wrong, it will fall down faster if it jumps down anywhere. No matter if it does not matter!

 

[Lord_of_sausage]

Nice Painting Pyritie ^^ like that little stickamn in the bottom xD
+Rep xD

 

[Pyritie]

It took me like 30 seconds.

Trust me. I've done far better. (HINT: Click the "deviantART" link in my sig.)
