[Library] Quick Gradient Library

[HugoBDesigner]

So, I've always wanted to make some gradients, but LÖVE doesn't support it. So I made a quick library to make various different types of gradients in any shape you want (circle, rectangle, polygon, even lines!).

Update: Now this works for Löve 0.10.1, and I've updated the code so that having the gradient images is optional, not mandatory. If the gradients folder is not available, the program will now generate the images for you!

Just call require "gradient" and you're done!

How to use it:

Code: Select all

love.gradient.draw(function, mode, centerX, centerY, width, height, color1, color2[, angle, scaleX, scaleY])

Function: A drawing function (like with love stencils).

Mode: A gradient mode (linear, radial, angle, rhombus or square).

Center X: The X center of your shape.

Center Y: The Y center of your shape.

Width: The width of your shape (regardless of rotation).

Height: The height of your shape (regardless of rotation).

Color 1: The back color of your gradient.

Color 2: The front color of your gradient.

Angle: The rotation of your gradient image (default: 0).

Scale X: The scale factor for your gradient's width (default: 1, flip horizontally: -1).

Scale Y: The scale factor for your gradient's height (default: 1, flip vertically: -1).

If you have any feedback, error or feedback, please let me know.

Oh, here's an example (use the keys "WASD" to move the square, "TAB" to switch between gradients and "QE" to rotate it):

Aaaannd... A screenshot:

Oh, thanks for letting me know! It's a pity that Github couldn't support the .zip file, so I uploaded it in the main post (and removed from Github).

I'm not sure why github would not host data in a repo as is. Here's an example of it working; https://gist.github.com/josefnpat/2ef59aab6d133478dc4a

Huh... Then I'm probably missing something really obvious here... As I said, I'm a real noob in terms of Github

Nice little lib! I've forked it for my own nefarious purposes, I should combine it with the gradient generator I wrote a while back for some extra features (arbitrary gradient stops)

[HugoBDesigner]

Alright, decided I should update this library. I gave up on GitHub because I'm never getting used to that.

I've updated the code to Löve 0.10.1, as well as made the gradients folder with the images optional. If you don't download the images, the program will automatically generate them for you!
