how not to code: A cautionary tale


Making great headway with the farming system at the moment with the bulk of the code concerning crops out of the way. but whats been stumping me for days was getting tools to trigger the correct events on the plants. This is also the start of the tool system so alot is riding on getting this first bit right.

Tools can have different grades like in Harvest moon so I've had to account for this in the use method which will need to take grade and the amount of time the button is pressed to control the outcome of the use. easy enough in the end but then came interaction.

After getting the charge value and the tool type the tools unique behaviour will be called. in the case of the watering can it just needs to detect a tilled crop tile and then call it to carry out its own watering method. Send message allows you to trigger public methods on referenced objects in unity, and because its more hit and miss it means it doesnt matter if it fails to find anything. At least when you notice youve not put the capital in the name of the method you've been trying to trigger for an hour.

to detect crops a boxcast is used and everything it hits is stored in an array. the array is then fed through a quick loop that uses send message. The crop picks this up. alters its sprites, then reports the change to the field data

Its been a long one getting it ready and it still needs a few minor tweaks and of cause animations. but the functionallity of the watering can can be easily modified to edit other crop data and just like that we've got a hoe and a scythe.

Available for testing now

Wall height is being adjusted to accommodate things such as stages and lighting while also giving animatronics more breathing space.

VERY early test of very basic systems in my new project. Do your work, keep the lights on, and everything will be fine. I really want to gush about some of the things not seen here, but will save that until they can be shown off. FnafKit who?

Finally, you can sell the fruits/veg of your labour. :)

Character customization: How and why bother? (expand)

Buttons jump scare test shot

I know updates have been slow but there really isn't much to talk about when you're just tidying up existing code. We're looking at updating the art style to be just that bit nicer. The crop system working with an overhaul to interactions with tools.

Light menu is still undergoing it's refit, some behind the scenes code changes making it easier to edit multiple lights. A light will also toggle on/off depending on its intensity. So custom events don't need to be loaded with two different commands.

Asking the big questions today. We won't support changing your characters outfit or gender but you can give our beloved testguy a name. Character customization will come later, as it will take planning to get it as versatile as we want at the moment.

Finally, I've had some time to do some more work on the recode. There is hardly anything to see except for this utilitarian clock which can be swapped to 12 and 24 hours in settings. The lighting again changes through the day too.
