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.
