Alpha Blending?

[DevBug]

I'm new to Love2D; but not to programming. I want to know if I can have more control over alpha blending. It doesn't matter to much to me because I can probably produce the effect I am looking for without full control. All I found was BlendMode.

You can set the alpha of anything by using love.graphics.setColor(r,g,b,a). Also, Love fully supports .png images with alpha.

Also, welcome to the framework and the community.

Thanks, Taehl. I'm afraid that I didn't make myself clear. I will probably extend love when I need to implement lighting.

I'm thinking that I'll implement it like:

Lua

Code: Select all

love.graphics.setBlendState('func', 'always')
love.graphics.setBlendState('src', 'zero')
love.graphics.setBlendState('dst', 'srcAlpha')

DirectX (I know Love uses OpenGL)

Code: Select all

Device->SetRenderState(D3DRS_ALPHABLENDENABLE, TRUE);
Device->SetRenderState(D3DRS_SRCBLENDALPHA, D3DBLEND_ZERO);
Device->SetRenderState(D3DRS_DESTBLENDALPHA, D3DBLEND_SRCALPHA);
Device->SetRenderState(D3DRS_ALPHAFUNC, D3DCMP_ALWAYS);

Here: love.graphics.setBlendFunc.
