Full Lifecycle Plant script

From Creatures Wiki
Jump to navigation Jump to search

This is a CAOS tutorial in the form of an in-depth analysis of an agent.


Introduction[edit]

Sharmflower sprite images.

This plant script has a full lifecycle and is interactive for creatures. The fruit timer script uses subroutines to check the environment and determine whether it's ok to grow, but the plant itself uses valid logic statements to govern its' timer. It is useful to use the CAOS Tool or another highlighting tool because they can make the CAOS syntax easier to read.

CAOS2PRAY[edit]

Monk, ready to use CAOS2PRAY.

CAOS2PRAY is a feature included with RProgrammer's Jagent which allows the coder to not have to code a separate PRAY file in their agents. This chunk of code goes at the top of the COS file, and when it is dragged and dropped onto Monk, compiles the cos file, with its dependant sprite file, into an agent that will be easy for everyone to install and play with. For more details on CAOS2PRAY, see CAOS2PRAY: An Easier Way by Amaikokonut.

Initial installation[edit]

Installs 30 fruits in the DS norn meso, using the sprite file tutorial_seed.c16.

Fruit timer script[edit]

Fruit timer script - first checks there aren't too many fruits nearby, then checks if the fruit is in water, then tests the environment for light, heat and nutrients (and then if there are enough, the plant grows, using the sharmflower.c16 file) but if there aren't enough, the fruit goes dormant and eventually is killed.

Plant Hit script[edit]

This script reuses two pieces of code from previous scripts: it stimulates whoever hit the plant as per the push script, and it uses a bit of code repeated from the timer to make the plant grow down if it is hit when it is more than just a seedling.

scrp 2 4 1000 3
	targ from
	stim writ from 84 1
	targ ownr
*the plant grows DOWN if it is hit.	
	doif pose gt 0

Remove[edit]

This simply counts through all the objects in the world with that class number, removes them, and then removes the scripts that belong to that class number. It's important to double-check the class numbers here, and make sure that all SCRPs in the object have a corresponding scrx.

Moving On[edit]

  • Change the genus to be a bad plant (2 5 1000 instead of 2 4 1000) and change all three stimuli to 83, "Danger plant", instead of 84, "Friendly plant".
