Directions of the trigger point with polar offset

[creyzi4zb12]

Ehllo, I have a question regarding a certain trigger.

The trigger reads like this
Move a (unit) instantly to (point with polar offset)

Move (footman001) instantly to position of (footman001) offset by (x) towards (y) degrees.

What does x and y mean? How do you read them as directions?

Thanks in advanced to all who help!!

X and Y are coordinates, real values.
You can look them in the left-down corner in the editor.

Polar offset takes not cooedinates, but degrees (real values too).

EDITED: Coz I didn't understand ur answer before..sorry

So Polar offset degree x means?
degree y means?
I think that one of those degrees refers to the point where the unit is facing. But where is it? Is it x or y?
And what degree is north? south? west? east?

Sory for so many questions!

The first changeable field is the base point. The second changeable field is how far it is from the base point. The last changeable field is the angle, where 0 is east and 90 is north (these are degrees)

 

[creyzi4zb12]

What's a base point btw? I know what y means right now!! tnx! yay!!

 

[Day-Elven]

Base point is the current position of unit in your case.
Don't forget to strore it in variable to prevent memory leak.

 

[Avator]

Base point is whichever point you want. And about X and Y: As said, those are coordinates. X is horizontal and Y is vertical when facing north on the map.

 

[creyzi4zb12]

So if I put 90 on x and 90 on y...where will the object move? Will it move southeast? or northeast or etc. when facing normal game camera.

_____90

180<-o->0

____270

Ah, that's better thanks to all of you guys..I now understand it clearly!

 

[Avator]

TheBlooddancer gave an example of degrees, not coordinates. For coordinates, you have it like this:

.....Y+......
X-...0...X+
......Y-.....

So up on the Y-axis is higher, down on the Y-axis is lower, east on the X-axis is higher and west on the X-axis is lower. Very simple.

 

[Justify]

And that has nothing to do with the question?
Saying that x is the x-axis and y is the y-axis is just false... he inserted those variables in the fields and in this case x was the offset and y the angle.
He also could write:
Move (footman001) instantly to position of (footman001) offset by (NODAMNXAXIS) towards (NODAMNYAXIS) degrees.
and it wouldn't be coordinates either :/

 

[TheBlooddancer]

Oh, sorry, i didn't bother to read your posts, so i just thought that Polar Ofset had to do with the degrees.

 

[creyzi4zb12]

So south and west are negative values?/If you wanna make an object move instantly to south or west you gotta put on negative values?
Is that it?

"Move (footman001) instantly to position of (footman001) offset by (x) towards (y) degrees"

okay. let me break this down for you. the X you refer to is HOW FAR to move the footman from THE POSITION OF THE FOOTMAN. X is measured in pixels (i think), so this number is usually in the hundreds.

Y is WHICH DIRECTION to move him in. Y should be a number between 0 and 360 (in degrees °). Y = 0 mean east, Y = 90 means north, Y = 180 means west, Y = 270 means south.

Example: x = 100, y = 90. The footman will be moved 100 pixels to the north of its original position.

 

[Day-Elven]

So south and west are negative values?

True. If you want to move him to south / west, use negative offset.

Just ignore the stuff with the coordinates, it has "nothing" to do with the PolarProjectionBJ. Its just idiotic to use a negativ offset with 0 degree when 180 degree and the normal offset does the same.
Read the stuff from maskedpoptart and be happy

 

[Day-Elven]

1. He means negatives of real location values, not polars.

2. He can make it on GUI without BJ

function PolarProjectionBJ takes location source, real dist, real angle returns location
    local real x = GetLocationX(source) + dist * Cos(angle * bj_DEGTORAD)
    local real y = GetLocationY(source) + dist * Sin(angle * bj_DEGTORAD)
    return Location(x, y)
endfunction

Thank you for that info, that was all I needed to know..I keep on getting confused as to why there were two slots.
So this means,
that (x) has nothing to do the south, west, east coordinate thingy but has something to do with non-other than the distance of where the unit will be placed.
And (y) has something to do with the south, west, east coordinate thingy.

One last question..What are the common values in (x) used to make a unit look as if it is jumping or being thrown to.

 

[Avator]

My sample was with real X and Y axis. That means I was referring to the 'Point with Offset' command. maskedpoptart is referring to the 'Point with Polar Offset' command. The first is only with coordinates, and the second is in a certain angle for a certain distance.

 

[Day-Elven]

What are the common values in (x) used to make a unit look as if it is jumping or being thrown to

It depends on many things: spell, specialeffects, hero model, map size, map type...
Look jumping systems in spells section.

 

[Justify]

It depends most on your timer period.
Example:
Jump lasts 1 second, timer has a period of 0.04 seconds.
-> the timer will run 25 times. If you want the unit to travel for 1000 range the small offset per calculation will be 20
Most times the values are between 5/20-40, but you should just calculate it.
