accès à la touche + (shift =)
« Reply #20 on: May 03, 2020, 04:35:03 pm »
Bonjour,

tout d'abord, je suis débutant sur SFML (et en programmation en général) mais j'ai bien réussi à mettre en place une chaine d’événement clavier fonctionnelle dont je suis satisfait.

Mon problème est que je cherche à accéder à la touche + (shift =) le code ascii est identique à celui de la touche + du pavé numérique mais apparement SFML n'utilise pas ce code ascii pour accéder aux touches.

En effet mon programme ne répond pas à + (shift =) alors qu'il répond à + clavier numérique.

Comment puis-je accéder à cette touche, elle n'apparait pas dans sf::Keyboard Class Reference

question subsidiaire, est il possible de forcer le shift pour qu'il soit activé tout le temps dans le programme ?

Merci d'avance

RLF

Retrieving + key with (shit =)
« Reply #21 on: May 03, 2020, 04:56:21 pm »
Hello, i'm new to sfml and rookie into programming.

I already set up a keyboard event chain wich is working and i'm happy with it.

But i need for some purpose to use the + (shit =), it shows Ascii code 43, same as + key on numerical keypad.

+ (shift =) is not triggering my event, it seems sf::keyboard::Add is only triggered by keypad.

Is there a way to use this key wit sf::keyboard ?

Bonus question, is it possible to lock Shift key in the program ? in order that keyboard numbers (not keypad) are always active in front.

thanks by advance,

RLF

Texture smoothing, window stretch, white/grey pixels
« Reply #22 on: May 03, 2020, 09:45:18 pm »
Is there a technical explanation for why some textures might have these artifacts when stretching with texture smoothing? Is there something I can do to the "faulty" textures to help them along and remedy this? Stretching the window with smoothing enabled is quite desirable for me here, so I'd like to do something other than just turning smoothing off.

If it can look fine for some textures then surely there's a way to get it to look good for all of them.

I want to check if a sprite is under another sprite's transparent part (textured with a png). I haven't really found a solution, is this even possible in SFML?

Forum database errors

Hi

It seems that the forum causes database errors when creating a new post, or doing a search.

We're aware of these errors, we're investigating and hopefully we'll fix that soon.

In the meantime, you can stop sending me PMs or e-mails about it ;D
