Advice on 'borrowing' TFTD sprites and sounds
« on: April 05, 2018, 10:05:57 am »

Since all those cool aliens and items and map objects and tiles in the correct art style are just sitting there, I though I'd ask. Are there any file format differences in terms of how sprites are handled or other hidden stumbling blocks? I also know that the two games handle palettes differently, so any advice on how to deal with that as a complete noob would be appreciated!

And finally, does anyone have any advice on colour swaps (changing the colour of lobstermen and switching the sonic weapon sprites to a base colour of dark grey rather than blue-green are my best examples)?

Palettes are different, the rest is more or less the same.

Conversion is best done by:
1. ripping TFTD image using an extraction tool (e.g. BB's toolkit)
2. converting it to 24bit bitmap (RGB)
3. then converting it into an 8-bit PNG image in a corresponding UFO palette

Any recoloring can be done between steps 2 and 3.

EDIT: a lot of conversions have been already done by various mods/modders... maybe you can reuse some of their work...

Thanks, this gives me a place to start :)

The rulesets make changing the in-game properties very clear but the graphics stuff is giving me minor conniptions as I have absolutely zero experience with such things.
