Graphics / [SFML2] Bounding boxes around sf::Text characters

« on: September 27, 2011, 02:58:53 am »

Any chance you're messing with OpenGL directly? seems like a possible blending state gone wrong, but at the same time i wouldnt bet on it

Maybe its something Mac specific, to which i cant be any help

Graphics / How to make a sprite that scale keeping the border radius?

« on: September 27, 2011, 02:56:18 am »

I think you're looking for a simpler version of something like the box model in  web languages.

In your place, I would make your button class with some functions to set this "box model" sprites.

Then, when you need to draw, it should go something like:

- draw corner sprite at button top-left position (pos).
- draw top sprite at pos.x + corner.width and with its width set as button.width-corner.width*2
- draw corner again, rotated.

-draw left sprite at pos.y + corner.height and dimensions as button.height-corner.height*2
-draw center sprite at position (corner.width, corner.height) and set its dimensions to be the same as top sprite for x and left sprite for y.

.. I think you can figure it from now!

Hope i helped and that i got to the point of your question.

Graphics / Using SFML in a resizable QT-Widget

« on: September 27, 2011, 02:41:23 am »

Firstly, the sf::RenderWindow should always fit the client area of the widget.

That means the rect that can draw things, coincides with the widget's rect, except for some possible border/margin.

Since the sf::RenderWindow took an external window handle, it should work as a proxy for the real window(the qt widget), meaning that if the widget resizes, its slave RenderWindow should get the Resize event too!

Once you catch that event, you just need to act acordingly, which normally means configuring the view for the new size!

Hope it helps!

General / Adding 2 Events in an SFML Application?

Whats the point? If you got all events left in the first loop, why would a second event loop work at all? it just skips.

Audio / sf::soundbuffer plays no sound

Maybe you're creating those objects inside a function, so they are destroyed automaticly at the end of it?

General discussions / Your opinion on the functionality of a template dynamic list

« on: September 05, 2011, 10:43:02 pm »

//What do you imagine these do, and what do you imagine they return?
TemplateList++;
TemplateList--;
--TemplateList;
++TemplateList;

 - I could only see this as iterating the list, increasing and decreasing an internal iterator!

TemplateList = Item;

Makes no effective logic to set a list as one item, but if you make it a += its a perfectly acceptable "Append"

//What do you imagine this should return?
(!TemplateList) - makes no sense to me, if its a template, the any object won't have a common logic evaluation. Therefore, what the hell wold be a negation of a list of any kind of object? Cant think of anything

Hope it helps

Graphics / Can Someone Help With Loading A sprite

It looks fine, normally.

Maybe you are just missing Release libraries with Debug build, check everything and try again

Graphics / Best way to achieve parallax scrolling?

« on: September 04, 2011, 02:05:39 pm »

Changing the view should be a simple matrix multiplication as far as i know, i dont think it would be slower than changing the image any other way!

And if you dont want to change your approach, just make your "player_movement" the difference between the new passed camera-center and the previous one Should work if my mind is not failing

By the way, how do you guys go about those landscape images, eventually they will exceed your gpu limitations in width. Do you tile a few images or what?

Graphics / Additional Windows?

« on: September 04, 2011, 04:26:07 am »

You actually need to handle events for all windows opened in a queue kind of way.

So you just have all the windows in a list or something and do something like:

Code: [Select]

foreach w in windowList
        Process w Events

If you are going to stuck your code in a while loop that doesnt want to end, at least make sure all important code is in that loop. or better, dont do the loop, and invite the new windows into your main loop code as i said!

Hope it helps!

Graphics / Best way to achieve parallax scrolling?

« on: September 04, 2011, 02:10:58 am »

I think i know a good solution, lets check on that

Lets call any parallel screen, that needs scrolling at diferent speeds, a layer.
Lets say a layer has a view associated.

When a view is moved, it is moved by a certain amount.
So, a good idea would be to add a speed_factor property to each layer, which multiplies the amount of movement the view suffers.

When your character moves, it will describe a movement along the axes, lets say player_movement variable.

normally, so the main layer view moves along with the player, it moves at the same rate, so it moves by player_movement.

To keep this afirmation true, the main layer speed_factor would be 1. This way the main layer view would follow the player exactly.

Now lets say a background layer should never move. Just assign it a speed_factor of 0, it never moves a inch.

And now just play with that speed_factor for anything in-between static and following the player.

This approach is so simple and effective that you should even achieve dynamic parallax scrolling easily, changing this value acording to your own algorithm. All you need is actually speed_factor and player_movement

You could even compute the speed_factor acordingly to the layer width, so when the main layer is on the end, all the others are too

Tell me what you think, if it is not clear, tell me too

Network / GetLocalAddress doesnt seem correct

« on: September 03, 2011, 01:22:57 pm »

Windows 7 32bit !

I have a really simple ISP service through ADSL. I own a DLink wireless router, to which the laptops in my house connect. My computer connects directly via RJ-45 cable.

My computer and the laptops work fine as a LAN, even allowing file sharing etc.

Thanks

Network / GetLocalAddress doesnt seem correct

« on: September 03, 2011, 12:11:02 am »

When i do this:

sf::IpAddress::GetLocalAddress().ToString();

I get 127.0.0.1, i was expecting my LAN address 192.168.10.2.

Any other way to get it?

Thanks
