Repeating a texture when using a tileset
« on: March 03, 2015, 11:15:38 pm »
For my basic "obstacle" object, I have sprites which have a width and height which is larger than those of the textures they are using. In order fix this, I use texture.setRepeated(true). However I want to use a tileset such as this one when I have multiple textures, using the sprite.setTextureRect() function in order to select the right texture. At this point, I can no longer have a repeating texture. How can I fix this issue, such that I can having a repeating texture for a sprite, whilst using a tileset and the setTextureRect() function SFML provides?

How about just drawing your sprite repeatedly at all the positions where you want it?
Yes, that's a lot of draw calls and not the "optimal" solution, but usually it is "good enough" performance wise.
Or you could use a sf::VertexArray - see also the tutorial entry.
You could of course also just use different (repeating) textures for each of your sprites - although that feels kinda horrible, but it would work...

Is there no simpler solution? I have a "draw" function which takes a sprite and a position, and I would be great if the texture was looped for the sprite object itself.

Nop.

Can one sprite support multiple textures in it at once?

No.

Ok thanks a lot for your help :)
It seems the best way to do it for now is just to add a "repeating" boolean to my draw function, and then draw the sprite multiple times. Thanks for your input.

When using a sprite atlas as shown, do yourself a favor and look at sf::VertexArray. It's just the best solution to your problem and scales in the long run performance-wise.
I know that for sure, as I just conquered the same "problem" ;)
