Passive spell help

[Drain Pipe]

I was thinking after gettin some feedback for my spells that i;d make a different one since after thought it seemed very unbalanced. Anyways, I want to make a spell for one of my slow players to increase his speed the longer he is in motion and then add the increased speed to his attack. I just want to know how i can detect when he is in motion and when he isn't.


I figured i'd make a half second looping trigger that checked for his position and added a value to his speed if his position wasn't the same.

Now the problem with this is running in between units so i figured after a certian speed was met he's start pushing units out of the way and after that he also start damaging unit's he pushed. As he maxed out his pseed wouldn't increased, but rather his attack damage. the only thing i don't know about is moving the unit he is trying to attack. I suppose i could make an exception so it doesn't to allow him to easy get to that unit and finsih it.


Any thoughts on this spell? Could it be balanced, or would it be too overpowered? (keep in mind that the unit who gets this is the slowest naturally and that it takes a good 3000 distnace or so to acheive full speed. The only thing i'd have to check is his movement angle and make sure to cut his speed bonus by a value (like 250 or so) if he turns 180 degrees and take and lower the penalty the straighter he runs. This will keep him from running in circles to increase momentum and make this spell used to catch up and finish of targets much like his other spell but less cheap as he can stop and be killed in the process or even lose his speed bonus if he's stunned. Perhaps even make him leave a unit trail to confuse enemies.


The only thing is i'll need to make his max speed around 700 or so so he could easily catch any unit running full speed for a good quick attack.

Anyone know how to change that? Can i use the shift thing (it can't be triggered movement he actually has to be moving that fast.)

That's pretty much it.

 

[Drain Pipe]

Why can no one ever answer?

I mean i've heard people answer easier questions.

I just wanna know what i;d need to do so that this trigger isn't overpowered and so that he slows down when he turns, but he slows down the more he turns (the maximum amoutn of turning being that of 180 degrees.


Don't tell me no one (not even daelin) can tell me how this can be done.

 

[Xeridanus]

you didn't give them very long to reply.

This sounds very difficult, but units have a propulsion window which is how far off stright forward the unit can go forward. eg. just say the propulsion window is 60 then if the unit is ordered to move 25 degrees off the direction hes facing then he can start moving striaght away but if hes ordered to go 120 degrees then he'll have to stop and turn on the spot before he can move in that direction.

My sugestion is that if he stops he loses all of his speed bonus, i think this should be easy to do

 

[Daelin]

Sorry, I didn't notice this thread. And besides, if you posted it 11 hours ago or earlier I wasn't online since I was sleeping (I'm in Romania, +2 GMT). If you posted it earlier, sorry.

Ok, the idea would be indeed to always take two points. You would need to work with timers. If you know JASS and you know handlers it will be piece of cake. If you don't, wait a little bit more since I think this afternoon I will finish my basic JASS tutorial. With it you can do locals and other stuff (but handlers not yet).

Anyway, you have a timer which everytime it expires it checks the last position of the unit (stored into a variable) and the current position of the unit (which is (Position of YourUnit)). However, the idea is that you should also have stored the angle between the last two positions into a variable. So you should permanently have another angle between points into a variable. Now, if the difference between (angle between the last two positions) and (angle between alst position and current position) is x (depends on what you want), then you decrease its speed. Else, you check if the unit changed its position and if it has you increase its speed. Sounds complicated but if you don't get it, I will try a script.

And you have my apologeze again because I didn't answer fast enough for you.

[Drain Pipe]

well sorry to burst your bubble daelin but i believe i;ve tried that already and it worked fro 3/4 of all scenarios. The problem with simply subtracting the angles is that after you get to 359.99, you go back to 0 and then 1 and so forth. so the editor checks all of the short angles only up from 0 to 180. everything after that will screw up and deduct the wrong amount.

Anyways, since it's been almost a week since i posted i figured out a decent enough way for this which was only to reduce the momentum if he stops. Otherwise this ability takes too long to powerful without being overpowered. So it doesn't matter any more.

However, i have a new question i think yuo could answer Daelin.


Do you know how i could import and inverted parabela and use that to make a jumping arc?

 

[Daelin]

Of course... The idea would be to know what's the distance between the points and how much you need to wait. Things which can be obtained through a formula by Vexorian:

SquareRoot(Pow([Start Point x]-[Destination Point x],2)+Pow([Start Point y]-[Destination Point y],2)) / Unit Speed

This if you make the unit move itself. If you move it manually just take the duration in which it would be moved.

Now, the idea would be that in the first half of the period to have the unit rise up with the Flying Height action. In the second half it would fall down.

The problem is to have it move smoothly. You can simply order the unit to move itself but if you do so, animations will screw up. So instead, you have to move it manually using handlers with JASS. If you can do this with triggers, super. But I never succeeded to make it move really smooth with triggers.

[Drain Pipe]

well thanks for the formula. I've been trying for quite some time. I'll remmeber to ask you since you're quite a wiz with mathematics.


Just one more thing as a function do go like this

Set Height to (all that that you showed be)

And do i base it off of current position - total distance? Well i'll fiddle around with it but if you could post that yeah...that would help me out a lot.

 

[Drain Pipe]

Wait now i'm stuck, by X and why as that finding coordinates for points or is X siatnce and Y height at distance? or what?

WHY AM I SO CONFUSED?


[edit] maybe if you knew what i was doing then you could help me. I basically devised my jump spell into 3 triggers; 1 to initiate and set it up, 1 to move him froward and 1 to move him upward based on how far he's gone.

Maybe Showing you these will help because i'm confused and i'm not sure how to use your formula. I found the distance byt mesureing the distance from my catser to the point and storing it. Then i made a trigger that moved him by a a constant value depepnding on the origional distance and finally i got something to change his height based on that. Here are the three triggers, perhaps you can show me how i should set it up.

anyways :

So yeah i'm going to assume that all of this should be done within 1-2 tirggers and that height and distance should be made at the same time.

Perhaps i can use a physics formula for an arc instead to make one more real....

Anyways, perhaps you can tell me how to fix mine. because my way seems to have no connection with yours.

 

[Daelin]

To make a real parabola I think you might indeed need to know some trigonometric formulas. And to be honest, I don't know much trigonometry yet. Some such shapes are perhaps difficult to make. Some guy already made a leap, but I'm not sure it is into a parabola. Look over it!

~Daelin

 

[Drain Pipe]

I did and no it was an imination much like mine. So yeah it didn't help. I suppose if mine is slow enough it doesn't matter, but meh maybe vex knows how.

 

[Chuckle Brother]

Hmm there must be a physics equation that would work for this. I'll take a looksie over my notes and see what I can find, maybe something in the projectile motion stuff

 

[Daelin]

As far as I know, there is a mathematical function which creates this parabola. It's a second grade function (unfortunately) and I'm not sure what it is yet. But as soon as I get to it, I'll make sure to announce you. And yes, I made some parabola at physics as well but it had nothing to do with creating it, just with the uniform accelerated movement or something. And I don't think this would help in WE.

~Daelin

 

[Xeridanus]

Here's the Formula for a function that keeps his height the same no matter what the distance:

y=Height
x=Horizontal Position
h=Max Height
d=Max Distance

y=(h/((d/2)^2))*x*(x-d)

If you want him to go higher the further he jumps then use:

y=x*(x-d)

Any Q's or more formulae just contact me and i'll see what i can do. Hope it Helps.

 

[Drain Pipe]

Um i can see a flaw in it though: when the distance is 1, the height won't be the same as when the distance is 599 if the max distance is 600, accoring to your formula. thta will only work for half the way. He'll start high and slwly drop down. My question is, will this be in the form of an arc?

 

[Xeridanus]

I get the same answer for both 1 and 599. do you relise that h and d have to stay the same? there is another mistake though. the whole thing should be multiplied by -1, otherwise everything is negative. keep h and d the same and follow the formula exactly and it should work. the part (h/((d/2)^2)) will boil down to an exact value. the x part means that y is zero where x=0. the (x-d) part means that y zero where x-d=0 or x=d. l8r.

 

[Drain Pipe]

Ok thx i'll try it
