Window / SFML 2, latest GIT, c++ SetFrameLimit not working

« on: January 31, 2012, 03:53:08 am »

SetFrameLimit is not providing a stable fps, for example

SetFrameLimit(60) will provide an fps ranging from 120 to 57

Expected variance of 57-62 instead of an 57-120, fps will spike to 120 infrequently but consistently hits 70-80 fps

Running Windows 7 (x64) 32 bit program, latest Git dump.

General / SetFramerateLimit does not seem to work correctly

This problem is also occurring to me on a Windows 7 (x64) computer, running the program in 32 bit mode, haven't tested in 64 bit mode.

EDIT:

this is using the latest git in a c++ program.

This can be fixed without casting coordinates to integers. I still haven't found a global solution which solves all the rendering issues (there really are a lot of them), but this particular issue is already fixed in the current SVN sources. At least that's what my latest tests showed ; feel free to test yourself on your own application to validate it  

firstly, it's not fixed .

second of all i believe that as you said, the window and scene are kept seperate.

so when calling app.Draw, perhaps then the scenes position vectors are translated to int's

Non-smoothed fonts are just ugly.

Honestly mate, thats just like saying "i think that nonAA fonts are ugly and therefore will restrict you from using them." is it really upto you to decide that?? by adding one function you can pass that decision from you to the user, and thats where the decision should be. hell i wanted to make the font purple with pink spots and the functionality was EASILY there, i should be able to do just that. just because you dont like it doesnt mean it shouldnt be there.

Hi, i'm an avid developer currently working on a 2d mmorpg.

along my travels i have come to rest on the wonderful api that is SFML.

now i just wish to post a few troubles i've had with the engine

Firstly, decimals and rendering.

when drawing to the screen, the float x and y should be cast to int.

why?

well, if you don't you'll experience strange rendering, positional and tearing glitches. where part of the sprite tears, or is compressed.

IMHO this should be fixed, as for me atleast it was confusing that when i started moving my characters they all of a suden became distorted.

this should ALSO be applied to view co-ordinates, as this has the same effect.

I would also ask, why sprite's require float X and Y coordinates, as from my experience you cant have half a pixel on the screen, as that doesn't make any sense.

If float variables are needed, atleast have an option when drawing to use non-rounded variables, or explicitly in the documentation refer to this drawing behaviour.

Another issue i have had with SFML is the font system, which in my opinion is a bit retarded...

firstly, i don't see why you couldnt just add an option to disable smoothing for sprites, it took me all of 2 minutes to add the code to the SVN release. 2 MINUTES, and it fit into the rest of the API

font->SetSmooth(bool Smooth);

Heres the code if you are indeed to busy

(goes into font.hpp)

void SetSmooth(bool Smooth);

(goes into font.cpp)

void Font::SetSmooth(bool Smooth){
texture->SetSmooth(Smooth);
}

i mean, really?

Other then this i have no REAL issue with the engine, it has done what it was supposed to do, at perfect speeds.

and to this i thank you Laurent as i'm sure most of the SFML community does.

Please Reply people if you would like to point out my stupidity, i love to learn and love criticism

Graphics / Position of an object whilst using SetScale

« on: August 30, 2009, 11:15:39 am »

when i set the scale of an object with center (0,0), its x and y position are changed :S

This is in the SVN sfml release

Graphics / image tearing???

« on: August 29, 2009, 12:15:35 am »

ok, this fixed the problem. but on another random note, my background which is 1px wide and 800 high, when stretched chages its origin by 100px, odd

Ok, will do laurent

just a heads up though, i dont use image smoothing, its FUGLY. specially for a sprite based pixel game. anyways i'll see what the sfml2 does for me

ah, yes a few minor glitches here and there, but overall ALOT more stable, wouldnt you agree?

aww ok, well do you think it could be that the x and y are at decimal positions?

If you havent realised, there is no image smoothing.

and you why cant i have frame limit AND vsync?

VSYNC is on, as is frame limit 60 fps

i tried disabling vsync, then frame limit, and then frame limit AND vsync to no avail
