[SOLVED] How do i transform a sprite with 4 coordinates (aka Vector2)s ?

[marbelynrye]

Given 4 points (or "Vector2"s) how do i transform a sprite to look like the images attached?

[eXpl0it3r]

Do you want to cut out this kind of shape from a texture?

[marbelynrye]

No, just transforming a image/sprite  (or "distorting" it to look like that)

[eXpl0it3r]

You could just use a vertex array, set the texture position and vertex position.

But this will lead to a potentially unwanted distortion, since the vertex array is made up of two triangles, that are shaped independently.

You may instead want to use Hapax's Elastic Sprite: https://github.com/Hapaxia/SelbaWard/wiki/Elastic-Sprite

oh this is exactly what i needed, thank you sir

having a hard time getting it compile, i'm probably an idiot but I don't think i'm doing anything wrong.
it's giving me linker errors

sw::ElasticSprite sprite(cattex);
sprite.setVertexOffset(2, { 150.f, -30.f });
 

1>main.obj : error LNK2019: unresolved external symbol "public: __cdecl selbaward::ElasticSprite::ElasticSprite(class sf::Texture const &)" (??0ElasticSprite@selbaward@@QEAA@AEBVTexture@sf@@@Z) referenced in function main

both .hpp files are present

If you use SelbaWard as a library, make sure you're linking it.
If you just want to include the specific files, make sure you've add the *.cpp files to your project.

ah i forgot about the linker properties
