Random map with 4 seasons,I have some problems on that...

[savagust]

I want to make a random map with 4 seasons.

The season of this random map changes every 6 turns.Each season affects certain types of terrain.

Since I haven't made anything like that before, code may be messy.

I have two main problems on it.

Firstly, I don't know how to make the season change every 6 turns but not every turn.Every turn is too often for me

Secondly, the season remains changing into Spring every turn.It cannot change into other seasons.The cycle of season that I hope is:Spring > Summer > Autumn > Winter > Spring...

I failed to solve the problems myself.
If someone can teach me how to do, I really appreciate

Code: Select all

[event]
 name=prestart

 {VARIABLE weather spring}

first_time_only=no

take a look in the Despair and Decay campaign. i mean the Haunted Houses scenario. there we change some cave tiles depending on the time of day. however i had to count the turns, so i am pretty sure that you can use the same system for the season changes you wish. just make macros for every season and call them on the turn when you need them.

i will see if i can make an example this weekend but maybe you want try it for yourself, since i can't promise anything.

Your suggestion helps me a lot otherwise I would not find a right direction to try to make it work.

Thanks for your attention and kindly suggestion

The trick is to use <ick>MATH</ick>!

if turns-((turns/4)*4)==0 then do_stuff_every_fourth_turn

this works because the division gets rounded. ive got a map with tides (water moves in and out every 2-4 turns) that uses this, ill try to dig it up and post the WML.

I am working on it smoothly with the suggestion of flava_clown

Thanks again, flava_clown

However, I still didn't know how to make the season change every 6 turns until now

May you post an example here?It would help a lot because I don't know where the equation should be added.

Thanks sparr

Code: Select all

	[event]
		first_time_only=no
		name=new turn
		{SETVAR temp format $turn_number}
		{SETVAR temp add 2}
		{SETVAR temp multiply .25}
		{SETVAR temp multiply 4}
		{SETVAR temp add -2}
		[if]
			[variable]
				name=temp
				numerical_equals=$turn_number
			[/variable]
			[then]
				{LOWTIDE}
			[/then]
			[else]
				{SETVAR temp format $turn_number}
				{SETVAR temp multiply .25}
				{SETVAR temp multiply 4}
				[if]
					[variable]
						name=temp
						numerical_equals=$turn_number
					[/variable]
					[then]
						{HIGHTIDE}
					[/then]
				[/if]
			[/else]
		[/if]
	[/event]

This changes from low tide to high tide and back every 2 turns. the .25 and 4 constants correspond to the 4 turn complete cycle, and the +/- 2 makes low tide start 2 turns after high tide. For 4 seasons you would have a 24 turn complete cycle, and you would +/- 0 for spring, 6 for summer, 12 for fall, 18 for winter. This would make the game start in the second month of spring, i think... Adjust all the +/- values to make the game start on a different 'month'.

Thanks so much, sparr!

I know how to do it now

[savagust]

I modified and added it to my code, but I don't know what I have missed, so my code doesn't work.

I would like to see the whole file so that I could find my mistakes by compare.

May you post the whole file here?

Sorry for bothering you again
