General / sf::Seconds delay?

« on: August 23, 2012, 07:01:17 am »

I'm trying to get a delay in between events. The point of this is so that when the user tries to move the character, they can't simply hold down the arrow key and fly off into the distance. Now I looked into the documentation for handling time, but all I could find was how to measure it. Now how to delay the program.

So is there any way to do this? I'm sure it's really simple, and I'm just not seeing the obvious here.

I don't think showing source here is necessary, but if anyone needs it, let me know.

For this case there's a documentation which shows you which functions exist and which don't...
i.e. all classes, sf::Rect, sf::Sprite, ...

getSubRect -> getTextureRect
getSize -> getLocalBounds or getGlobalBounds
...

I'm aware of the documentation, but I don't see anything on what function names have changed to.

EDIT: Alright, I figured out a way to do what I needed. Thank you for all your help.

I don't get your queszmtion...
If you want to use SFML 1.6 code in your SFML 2 project it's obviouse that it won't work and that you have to convert it.

Basically I need help with converting to 2.0.

Converting can get tricky sometimes. I mean, I tried to convert one sfml based file into 2.0 and even after it compiled the program didn't respond properly.

But at a first glance, alot of those errors seem to be because of thr new casing system.
e.g

Code: [Select]

sf::Sprite::GetSize -> sf::Sprite::getSize
//1.6                             2.0


I'll try that, see if it works.


EDIT: Well I did what you said, and now I'm down to 25 errors. Here's the source that I edited:

And here are the remaining errors:

Sorry for the double post, but I looked into the Wiki and found this:

https://github.com/SFML/SFML/wiki/SourceSimpleCollisionDetection

I included it into my project, but I get a ton of errors, most likely because it was written for a previous SFML. So I need help converting this old code from 1.x to 2.0, if that's in fact, what I need to do.

The source I'm getting errors in are at the bottom of the linked page above.

Also the errors I'm getting....:

So you know what to do right?

Well I would assume to convert into a .png. But I thought that the .jpg format was supported?

Alright, <iostream> works now. I just recompiled and it worked. Weird. Anyways, I switched to console, and turns out the problem is that it can't load "figure.jpg". The source is exactly the same as the source in the OP.

EDIT: Forgot to mention, I have the picture spelled correctly, in the same directory, and I can open it, but the error message from the console is as follows:

Failed to load image "figure.jpg". Reason: Unable to open file

I guess you already checked the obvious solution, i.e. a failure on texture loading

What would help us is to know where it stops. You can easily see that with step by step execution, or by adding output messages at relevant locations in your code.

Yea, that seems like the obvious thing to do. In that case, how do I get the console to work along side? Whenever I include <iostream> and use std::cout, nothing happens. Also, I'm using Visual C++ 2010 Express, and I created a Win32 Project.

EDIT: I included <iostream> and when I out put a string in the very beginning of the project, I get this error:

Error   1   error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'overloaded-function' (or there is no acceptable conversion)   


Also, this is the line of code causing it:

std::cout << "test";

SFML is a Simple and Fast Multimedia Library, thus it can handle all the stuff you can find on the feature list. For all the other stuff you'll have to program things on your own or use a diffrent library. You can find some tutorials about collision in the wiki section of SFML or just use google since the topic is generic and not bound to any library nor programming language.

If you need complex physics you can check out Box2D but the itegration with SFML isn't trivial for a beginner.

Btw. It's collision and not colission...

Ah, stupid typo, my bad haha.

Thank you for the links, I'll look into them.

Hi everyone, I'm hoping to write a 2D game in the near future, using SFML. I almost have rendering down, but now the problem I'm facing is learning how to get collision working. I can't find anything under the SFML 2.0 tutorials and was wondering if SFML even supports it. If anyone could point me in the right direction, I would be very grateful.

Hey, it's you again!

Thank you for having patience with me again hahaha.

For anyone else looking at this in the future, I solved the problem by adding "opengl32.lib" under additional dependencies under the linker settings. That solved the problem for me.
