Audio / Re: Audio crashes of exit

« on: September 24, 2013, 01:46:02 pm »

I am facing this problem too, self-compiled latest SFML 2.1 on Windows XP.

I think this bug should be fixed as soon as possible, it's been months since it was discovered, and a lot of users are complaining about it.

Is there any workaround (and with any, I mean even a very dirty one, as long as it works) compatible with dynamic linking? Modifying SFML source and recompiling wouldn't be an issue.

Yes, the pc I'm using to program (the one where the game runs perfectly) is quite old, as it uses an Intel GMA 4500M, whereas the pc's on which it doesn't run both have AMD video card, the first has an AMD Radeon HD 6670, while the second has an ATI Mobility Radeon HD 5470.
Thank you in advance!

General / Compatibility problems on different machines

« on: January 30, 2013, 10:14:57 pm »

Hello everyone,
I'm having a problem in using SFML. I'm working on a quite big project of mine using SFML 1.6 (Yes, I know I should go with 2.0, but I already started with this and I'd prefer to upgrade my engine to 2.0 after the release of this project, as changing it now would take way too much time) I've compiled 1.6 myself (dynamic linking) and, while it runs perfectly on my machine (Windows XP x86) while on an other pc (Windows 7 x64), it runs REALLY slowly (usually not more than 1 fps); not only that, the texts rendered with sf::String's appear as series of black squares of the size of the wanted letters. I noted, however, that this only happens with one of the two fonts I'm using (this looks strange, they're both TrueType Fonts, and are read well everywhere). Music, at least, seems to play just fine, it goes slow too, but not too much compared to everything else.
What could be the causes for all of this?
Thank you in advance!

Thank you anyway, I'll think about switching to 2.0

Hello Nexus,
first of all , thank you for the help. For the first tip, that's ok, as I don't have any problems with a second dat file. As for the second suggestion, I'm currently using SFML 1.6, while sf::InputStream seems to be included only in SFML 2.0. Any suggestions for version 1.6?

Audio / Streaming from DAT file

« on: November 29, 2012, 06:22:14 pm »

Hi everyone,
I'm currently working on a SFML project. In this project, I'm using a DAT file to store all my files (at the moment only images) to prevent users from modifying them. Now I'd like to store audio data (BGMs and sound effects) in the same file. With Sound effects there shouldn't be any problem, I can just load the data in a char* ecc.. Now I'm facing the problem of BGM streaming. How could I solve my problem? I could just load one whole track at a time, but then I would have a really big size allocated and I wanted to avoid doing so. Any suggestions?

Among the other member variables, my bullets have angle and a float named basetime, which says at what time the bullet has been shoot. Every time the game loop is executed, I save the frame time in a float and add it to TotalPastTime. Doing this way I have a whole set of instruments I can use to move the bullet: for example, I could make it move straight forward to the player with something like (I'm inventing at the moment):

On bullet's constructor:

angle=-atan2f(Player.Pos.y-enemy.Pos.y, Player.Pos.x-enemy.Pos.x); //Radians
Sprite.SetRotation(angle*180/PI);
 

And on bullet's move func:

Sprite.Move(cos(Angle)*speed*FrameTime, -sin(Angle)*speed*FrameTime); //speed is usually a raw number, not a variable
 

The above, when executed, makes the bullet calculate where she has to go, aiming to the player, and then, during the loop, it moves in a linear way using cos/sin for the variable angle

The basetime usually comes when I want to make more complex patterns, such as accelerating or curving ones. For example, accelerating bullets' move func could be something like:

Sprite.Move(cos(Angle)*(100+(200*(PastTime-basetime)))*FrameTime, -sin(Angle)*(100+(200*(PastTime-basetime)))*FrameTime);
 

In this example, I have a bullet which initially has a speed of 100 but, after a second, has reached a speed of 300.

But I also could stop the bullets for a while, (like TD fairies at the beginning and end of stage 3), and this could be easily done by checking the value of PastTime-basetime.

This is how I do it. There's only one thing left I have to tell you: Good Luck with your game!!!

PS. Sorry for my English, it's not my main language

Well, in my implementation, every moveable object has a basetime (float variable) and a move function which uses PastTime-basetime to calculate where the object is at a certain time. Move function are different from one another, so for a simple linear movement the position will be calculated with cos/-sin (sin is negative since sfml y is 0 on the top and window_height on the bottom), but when I want I can make something more complex by using the time variable, which allows me to implement curves, pauses for shooting sessions, and things like that. The best I've made until now is something which looks really similar to Mononobe no Futo's last SpellCard on Overdrive difficulty, with that sort of rotating flower with 5 petals, or something like Suwako Moriya's last one, with the circles of crossing bullets which come always more often.

btw, just out of curiosity, what did you use for position calculation?

Surely it's possible to implement movements in smarter ways, but if you think my approach is good enough for you, you can use it without any problem.

This is mainly based on an already existing game series called touhou.

Just to let you know, you really killed me with this post, I am currently writing a SFML Touhou-based bullet-hell game too... D:
As for me, I've already written the whole Engine, except for the audio part, and got two levels playable. 
Well, good luck with your game, I'm really looking forward to playing it
