General discussions / SFML and Box2d

« on: September 05, 2020, 03:50:41 am »

Hello!!

does Box2d converts SFML into a Game Engine ?

a pretty absurd question, but i still don't get what a Game Engine is, since many people have done games using SFML (indeed, a packt book exists)

Thanks.

General / set parent...

« on: July 16, 2020, 05:49:33 pm »

Hi
Im wondering if there is a built in set parent function ...
If not, then i have a raw solution but i don't know how elegant is it, is setting the position and rotation of the child object using the current rotation and position of the parent in the game loop....

Is that the only way to do it?

Thanks

General / BG & FG Level design ?

« on: July 12, 2020, 11:30:41 pm »

Hello!

I'm pretty new to 2d game development, i only worked on 3d and 2.5d views, but those are quite bit different since they are model based..

On 2d, how do you design your background and foreground's sprites for your level?...

1) Use big and long sprites as layers for all the level.
for instance,  a long 4096 x 256 texture that cover everything for your background, you put everything in that texture so do not need to repeat anything, the same for foreground alpha texture.  (This maybe absurd if the game is really long or need better bg details).


2) use single sprites repeating them on the whole level
reusing short textures like 128xx and 256xx as many copies over the level.  (To make game look good should be using many kinds of trees, rocks, plants and so....

3) any other?

Thanks..

General / Using opengl

« on: July 10, 2020, 05:10:15 am »

Hello!!

I'm looking for a way to do a game just like Donkey Kong Country from Super Nintendo, you know, the game is smooth, good graphics and animations.....

After seeing some showcases i saw that many of the games runs a bit lag, i don't know either if thats because recording screen or something else... so i investigated a little more and found that i can use opengl for 2d content which means that SFML by default does not uses openGl... is this right?

In such case, do you think i'm forced to use opengl to create something like Donkey Kong Country or the default SFML video system is ok?..

In case i need opengl, does someone has a good book or resource to learn SFML + Opengl?

Thanks so much!..

Edit:
I understood that SFML uses OpenGL, so i think i neee to focus on learning how to move sprites smoothly using time & physics..
