Projectile trajectory bug - Game Video and images included!

*** Since the beta bug reports forum changed, I am posting this here ***


Hello everyone!

I made this video to show what seems either a bug or badly designed projectile trajectory and errant direction.
This affects all ranged spells and I will be uploading the other videos to show.

It consists of a misplaced trajectory of the projectile/spell when on diagonals and horizontal aiming. It works as it should when aiming vertically to your character.

You can see what I mean in this video here: http://youtu.be/NPblo1-RE88
Second video: http://youtu.be/NT7sHbw0Fjo
Third Video: http://youtu.be/D-UvQJYnVFA

I will also be uploading other videos showing how you miss 90% of the time when pointing directly adjacent to the target if in a horizontal or diagonal direction.

Hope this video and the following ones I will be uploading will be self explanatory.

Thanks for your time reading and I appreciate one of the Devs commenting on this matter.

Thank you for the extremely detailed feedback. Videos of any problem/bug are always greatly appreciated.

I have seen your footage, and I believe that this NOT a bug, rather a simple misunderstanding:

Arrows are NOT fired at the point you click on. This is intentional. Instead, they are fired at a point approx. 1.6m directly above the point on the ground that you click, so that they travel parallel to the ground (assuming the ground is flat).

This allows arrows to travel past the point you click and to hit enemies in the line of travel. It helps, for example, when you mis-click near an enemy since the arrow can still go on to hit something, instead of getting lodged uselessly in the ground.

Here is a illustration of how the arrow is travelling. This is me using paint to draw onto one of your screenshots.


Note that the line from the click point to the character's feet is parallel to the arrow's flight path.

Thanks again for the detailed bug report, but I don't think this is a bug!

Rhys thank you for your explanation on this matter.

Though I understand your logic behind this now, the fact remains that in Action-RPG games I have played, none had this sort of aiming and they all had accurate hitting, you point the mouse, you shoot there, simple as it is.

The problem with adopting this technique to shoot, is that it mislead users into thinking the spell or projectile is going to hit the cursor, and if it doesn't hit anything it will travel off screen.

In no moment at all gamers would think it would hit the ground, it never happened in this sort of games and I would like you if possible to show me an Action RPG where you point anywhere in the screen and the arrow or spell hit the ground as a result of not hitting a target.

I do not feel this new aiming system benefits users and I have a very good friend who I called to play this game and he felt exactly the same way as I did, a proper "WTF!" moment.

Many countless times I was aiming at chests and the arrow would just fly above it... then I had to lower the aim and then shoot it...

yea this technique sucks change it dev i want to kit ground sometimes looks cool and useful for some skills like for example poison arrow to poison the area you like.

Indeed, and I would really like to see another Action RPG with an isometric view that has this system too.

I have never seen this in another game that is an Action RPG with top down view.

So I really, really, would like to see another game with this "common practice". :/
I heartily agree with m3lt.

It might not be a bug but it sure is a poor game mechanic. I was wondering why my arrows were going all over the place except for were I was aiming. It just feel clunky and anti-intuitive after 20 years of game playing.


Rhys the pic you "doctored" showed just how off the animation is. You should at least change the arrow flight so that it moves in the same line or parallel with the characters arm, the arrow coming out at the angle it does just looks like poor workmanship. Not to mention how annoying it is to use.
Ascension tied to Lab is the worst thing GGG has done...apart from GGG's philosophy on Trading. Oh and Gambling Loot boxes. And selling out to tencent.

I used to love GGG. I supported to ensure GGG remained independent, now I just wish I could get my money back. -_-

Absolutely my friend!

I really don't know why they had to change it in this game, all action RPG's I know of, use the usual system where you point and shoot and the projectile goes there.

As we can see from this thread here: http://www.pathofexile.com/forum/view-thread/72875

I am not the only one noticing this, so let's hope we can in the future see some changes regarding this.

And Chameleon, have you ever played any other top down isometric action rpg with a targeting system like this?

I haven't, and I am asking people around if they did so at least I can compare. :)

But the norm I see, having played games all my life, is that you shot to where your cursor is.
When I first started playing I really noticed that sometimes I missed by quite a lot. Mostly when trying to click on monsters as they moved. It seemed odd, but I hadn't really twigged what was causing it. The OP describes it exactly.

So many of the systems just feel very natural to a player of ARPGs, but this immediately felt a bit weird. If I understand correctly, if you were to miss click just "below" a monster, the arrow could go past "above" them on screen.

To me the most natural aiming would be to take the mouse position, convert it to a world space ray (must be doing this already) and if you want the arrow to fly at 1.6m above the ground, change the aim point to be the point along the ray where the ground plane is 1.6m away. You could calculate it using the angle of intersection with the ground plane(assuming the ground is always flat) and a bit of pythagoras so it isn't expensive.

It would probably take less than an hour to implement and try out.

I think it would feel way better and less surprising for the players.

Cheers!

Hehe :)
Maybe you missed like me here?

You are not alone mate, let's hope the devs can rethink this silly "ground/feet line of sight" they implemented and actually use the aim where our cursor is.

Noticed this too, wrote a thread about it before I saw this one. I really hope they change the aiming system to where you click, and not above where you click. The way it is right now just makes no sense. It's the first time I've ever seen aiming like this in a game, and from my experience thus far, it's incredibly detrimental to the game play.

I love the set up/game play of the ranger, but the constant having to worry about how far above my cursor the arrow is going to go, just ruins the fun of the character. It basically means you either have to directly click on the enemy to make sure the shot hits (And lets face it, clicking directly on constantly moving enemies, is not easy to do, even for experienced players.), or, just kite around, and use skills, ignoring your auto attacks almost completely, which just limits the game play options of the character.

I just want the arrow to go to where I click, like every other isometric game in existence. Not above where I click.

I love the game, but I want to play a ranged character, and this system makes it very tedious to play one. So I think I'll take a break from the game, and come back later, hoping that this system is changed in the future. It's a fun game, but when I have to constantly deal with a counter intuitive control scheme, it just ruins the fun honestly.
