Important info

:warning: Recently Grey Hack changed to character limit of tags per print line to 2048. Anything above that causes the image to be displayed incorrectly. So unfortunately for now images have to be very small.

Associated changelog for this:

- Fixed bug that could cause a crash and an unexpected game shutdown when using certain tags in scripting within an infinite loop.

Introduced via version v0.9.5683 (public) and v0.9.5905E (nightly).

:sparkles: I've created a BepInEx plugin which circumvents this issue: Plugin to fix current implementation

How to

Static Image

Static images can be simply transformed into TextMesh Pro Rich-Text tags by using:

gh-image-transformer path/to/image.png

Optionally you can also select the width and height. By default, it will resize the image by a width of 16px. If you want to resize the image by height just place a -1 at the spot of the width.

Keep in mind that the images should be kept below 100px since Grey Hack has a limit of 160000 characters for each print line. Please take a look here.

Via the additional options, you can also change the scale of each pixel.

GIF

GIFs can be transformed into TextMesh Pro Rich-Text tags animation frames by using:

gh-animation-transformer path/to/image.gif

The options of the animation transformer are the same as the ones from the normal image transformer. There is only one additional option which is about the delay between each frame.

Note: It is highly recommended to use either greybel-js or greybel-vs to import animations otherwise you end up with a lot of copy paste depending on how many frames the GIF got.

In case you are using greybel-js you just need to execute greybel path/to/image.src. It is recommended to use the --create-ingame flag to avoid copy-pasting all the files.

If you are using greybel-vs you just need to right click on the image.src and select build. To make it more convenient please make sure to activate the create-ingame option.
