Graphics / Re: Moving camera around, everything is getting a motion blur effect, how to remove?

« on: October 07, 2013, 02:54:22 pm »

With VSync it is still there, my GPU has VSync set to "Controled by application"
Withot VSync its still there unchanged, but allot of screen tearing occurs.

On my GPU i set all setting off or to lowest possible and the issue was still there.
I also tryed setting GPU to application control and all to maximum the issue is still there.

I will post minimal code soon.

EDIT::
It is getting so complicated about code, i am unable to reproduce the issue with sfml shapes.
I have complex way of holding/rendering.
Still working on it.

The effect occurs on anything being drawn.
Drawn a single rectangleShape on a black background and i got the same behavior.
I also

Code: [Select]

sf::ContextSettings constSetting = sf::ContextSettings();
constSetting.antialiasingLevel = 0;
constSetting.depthBits = 32;
constSetting.majorVersion = 0;
constSetting.minorVersion = 0;
constSetting.stencilBits = 0;
renWin.create(vidMod, string, style, constSetting);
Same issue.

Graphics / Moving camera around, everything is getting a motion blur effect, how to remove?

Hello, unsure if this is correct place to post this because i am unsure is this hardware or sfml related.
So to explain my issue the best i will first describe when it occurred.

I have a screen filled with map(as walkable terrain, grass), on this map there are sprites like barrel, houses and other stuff related.

The issue starts when i move camera, everything gets motion blur or like 60-75% transparency and is drawn again where it used to be before this loop, tried to get screenshot so many times but i failed every single time.

I do not understand what is the issue here, its like the old buffer got drawn again but with 60-75% transparency this time.
I do only have one display() call to render window and i am hoping you got some idea what i can do to turn it off.

What IMO i need to modify is GL states, turning off AntiAliasing and other shader effects, but i am no expect and i may be mistaken massively.

I do not notice the issue, somehow turning Vsync on makes it look even smoother.

Unfortunately doesn't work. ;(
I also have the same code on SDL and there it uses your solution since SDL_Rect positions are ints, but it shows the same problem.
Thank you anyway ^^
Im starting to think that my eyes see more frames that it should

Pass me exe file, i need/want to see that.

I used your code, just made the adjustments i suggested and it was fine, perfect movement.

Graphics / Re: Size max of an sf::Image

« on: October 02, 2013, 02:53:56 pm »

(like 2000000px * 2000000px).

Loading texture that big...
Stream it during runtime, it will take more process but its the only way for that size.
If streaming is out of grasp, split map its many little peaces and load/release as needed.

The choppy movement can be eliminated simply by passing int for position of sprite,rectangle...
Make two floats

Code: [Select]

float posX, posY;
Instead of updating the sprite directly, update posX, and posY.
Before drawing sprite update its position from posX, posY as following.

Code: [Select]

sprite.setPosition(static_cast<int>(posX), static_cast<int>(posY));

The issue is obviously with float type for position & how is drawing done.

Do following.
Add two floats.

Code: [Select]

float posX, posY;
Then for movement update posX,posY with coordinates.

Code: [Select]

posX += (move * dt);
posY += 0;
Before drawing, update sprite position from the posX, posY

Code: [Select]

sprite.setPosition(static_cast<int>(posX), static_cast<int>(posY);

Tada! smooth movement

Floats are inaccurate when so low.
Try following:
auto move = 100.f / 1000;
dt = clock.restart().asMiliseconds();

General / Re: Showing animated picture, how would i achieve that in sfml2.1

« on: September 26, 2013, 01:33:38 pm »

What i am trying is to show animated scene in .gif format.

You can't load animated file formats with SFML and maintain all the frames.

What is a way to achieve animation in sfml?

You use a sprite of which you change the texture rect over time. My Thor library also provides predefined functionality for animations.

Thank you on sharing that, i will see what i can pull out.

Graphics / Re: How to make VertexArray with RenderState semi transparent.

« on: September 24, 2013, 07:32:03 pm »

1280x1280 pixels is too high for very old graphics cards, but I think it's ok for relatively old graphics cards.

Oh good point.
I have not thought about that...

But does this 300x225 minimap area shows the whole map, or does it scroll? What I'm interested in is the total size of the minimap in pixels, not what you show of it. To know if you can pre-render it to a sf::RenderTexture safely.

Currently its drawing whole map witch is Huge 10k size width and height.
But i will eventually split the map intro small sections to improve performance so your suggestion would be more efficient and one i will use.

Splited map size width and height would be around 640pixels by 640 pixels. 32*32*4 in vertexArray size

Therefore my answer would be the size is 1280x1280 that i would draw to render texture

The map size currently is 1000*1000*4, i do not know what scale "big" is.

What is the maximum size of your rendered minimap, in pixels?

WINDOW_WIDTH = 800, WINDOW_HEIGHT = 600
sf::View viewMinimap is

Code: [Select]

viewMinimap.setViewport(sf::FloatRect(0.74f, 0.01f, 0.25f, 0.25f));
200x150 for minimap render in default but is resizable.
To draw minimap i use same code as i use for Map, i just change the view.

Size goes from +50% - 25%
so X goes from 200 default to 300 max 150 min
and Y goes from 150 default to 225 max 112.5

You should pre-render your whole minimap to a render-texture (it's not that big, is it?), rebuilding it when needed (user changed minimap size in options) -- or render it at maximum size and then just scale it. Then you just have to draw it with a sf::Sprite with color (255, 255, 255, transparency).

The map size currently is 1000*1000*4, i do not know what scale "big" is.
I have just made another vertexArray that holds another map with different color.
