heh, yeah

so yeah: blog for yourself. I didn't realize it when I started my blog, but it's actually a lot of fun to look over your old posts. That's where my amusement comes from

Moshe

@JohnMcDonald , I can relate.

Ok, this is annoying me. Stupid efficiency techniques on iOS. View recycling is gonna make me go mad!

hey all

doing tile based movement, the draw method does its own calculation for the inter-tile position adjustment

William 'MindWorX' Mariager

If you're using XNA, as a general rule, you should avoid too much computation inside the .Draw method, especially if it's easy enough to do it it in .Update. :)

JMRboosties

its not too bad i think.

let me show you somethin

@WilliamMindWorXMariager pastebin.com/d2xeFJh7

is that too much computation in the draw method?

William 'MindWorX' Mariager

Are you moving the entity in the .Draw method?

JMRboosties

William 'MindWorX' Mariager

Since it has nothing to do with drawing, you really should move that to .Update.

JMRboosties

10:40 PM

the actual movement of coordinates takes place in update

player position is coordinate based

William 'MindWorX' Mariager

Hmm, so it's just calculating the offset or something a long those lines?

JMRboosties

exactly

it works well right now

William 'MindWorX' Mariager

Ah. Well, it could be done in .Update, but as long as it's not an issue, there's no reason to not stick with it. :)

John McDonald

You have to note that the Draw() method is not guaranteed to be called for each Update()

JMRboosties

hmm

well here is what i was going to ask

the character heads stick up above their tile

William 'MindWorX' Mariager

10:42 PM

In this case it doesn't matter though, as it's just a rendering calculation and not a logic calculation.

JMRboosties

so any character drawn after another will stand on the latter's head instead of sitting behind

does that make any sense? let me get a screencap

John McDonald

it does make sense

I think you just need to draw stuff from the Top of the screen, downward

or... sorry

Top down, what was I thinking

William 'MindWorX' Mariager

And remember to not manually sort it!

That's stupid programming!

JMRboosties

@JohnMcDonald yea, thats what i need to do

William 'MindWorX' Mariager

If you're doing something like that, just use the "depthLayer" argument of the SpriteBatch.Draw method.

JMRboosties

10:45 PM

so i need some kind of logic method

@WilliamMindWorXMariager the trick is that i need to draw based on the character's position from the screen like @JohnMcDonald said

William 'MindWorX' Mariager

@JMRboosties Yeeees? :P

JMRboosties

anyone higher on the screen should be a layer behind

John McDonald

yeah, @WilliamMindWorXMariager is correct. There's a "depthLayer" that you can just pass in to the draw method

William 'MindWorX' Mariager

Which is why you should use the depth argument and let the SpriteBatch do the sorting.

JMRboosties

yea

William 'MindWorX' Mariager

10:47 PM

You need to translate the position to a value between 0.00 and 1.00.

JMRboosties

so in the main draw method, i need to sort the npcs and player characters based on their vertical coordinate

and give them an appropriate depth

William 'MindWorX' Mariager

No, you don't, you let SpriteBatch do that.

JMRboosties

i guess im a bit confused

wouldnt i need to let spritebatch know which char should be draw first->last

William 'MindWorX' Mariager

Just pass a depth like this SpriteBatch.Draw(..., (-this.Y / screenHeight))

JMRboosties

ohhh

lmao thats so simple

William 'MindWorX' Mariager

10:49 PM

Ehh, not exactly like that, but something like that, fiddle a bit with it. :P

JMRboosties

i get the strategy though

thanks!

William 'MindWorX' Mariager

You also have to change the sort mode to SpriteSortMode.FrontToBack.

Or SpriteSortMode.BackToFront.

Again, fiddle with it. :P

JMRboosties

haha will do

William 'MindWorX' Mariager

I spot a Super User here. points at @OliverSalzburg

grabs his torch and pitchfork

Oliver Salzburg

@WilliamMindWorXMariager Yeah, I've just been browsing through the rooms, looking for some activity :)

William 'MindWorX' Mariager

10:54 PM

We're usually kinda active here.

Of course, me and @John are responsible for like 20% of all messages, so I might be seeing more activity than most. :P

Oliver Salzburg

Heheh

I was mostly wondering what you guys are talking about here ;)

William 'MindWorX' Mariager

Uhm, the name of this room is Game Development, so I guess we talk about that... at times.

Oliver Salzburg

I have a brief history in 3D development, so, yeah

William 'MindWorX' Mariager

But mostly we just pester @Josh Josh with annoying remarks about how old he is.

Oliver Salzburg

Heh

William 'MindWorX' Mariager

10:57 PM

He's like REALLY old. Not even kidding. :|

Rumor is he knew Gandalf.

Soo, you're from Super User. I just got the Tumbleweed badge there. :(

Oliver Salzburg

Ouch :( What question?

William 'MindWorX' Mariager

Q: Turning on touch input without a touch device present

I'm trying to find a way to enable touch style input in Windows 8. Specifically, I want to have the touch friendly user interface. I'm looking at doing an experiment where I use a Wiimote for input, and I think the touch friendly user interface would make the experience much smoother. I looked in...

Oliver Salzburg

I just got a quadruple badge the other day :D Still very proud!

Damir

What's Tumbleweed badge?

William 'MindWorX' Mariager

It's pretty specific I know. :P

@Damir Asked a question with no votes, no answers, no comments, and low views for a week.

@OliverSalzburg I've reached the reputation cap by answering how triangles work. :P

Damir

11:00 PM

And how come formatting doesn't work for me?

William 'MindWorX' Mariager

A: Why does my object move faster at 45 degrees than at 90 degrees?

This can be explained with the Pythagorean Theorem, which is the following formula: a² + b² = c² In your case, when moving right, you're using (x:1, y:0) which gives us c² = 1 + 0 = 1 c = sqrt(1) = 1.00 When moving up and right, you're using (x:1, y:1) which gives us c² = 1 + 1 = 2 c = sqr...

Damir

LOL

It does now

Funny

William 'MindWorX' Mariager

Damir, if you have multiple lines it doesn't work.

Damir

Ahhhh

William 'MindWorX' Mariager

This
**doesn't**
work! :(
