new game (need loop fix)

[MrPixel]

so, this is the commented Demo for Chaos in L.A

2 problems:

1: i need a way to allow multiple choice through the IF-THEN statements
2: i need a way to STOP the choice and allow another if necessary. my goal is to allow multiple choices, but loop back to start upon death (the Hobbit for example)

e.g (go to house. you have found a gun, use gun on tank etc...)

but all i have is the IF statement and the if f is < > or = statements.

please help

this is the Demo

sorry if it's not in CAS form, this site can only allow 4 MB images

I'd recommend using a state machine for a game
You should have three sub states for each state, init, logic, and exit.
You then call a reentrant function repeatedly and change states when required. The game runs as a tick until the state changes.

um...in english?

Google for state machine and game

[MrPixel]

i did. no use

MrPixel,
Might help if we could see some code example of what you have that is not working.
You might not be that far along, though. It's OK if you're not.

i had deleted it. sorry. i could make an MSX version but the commands for lines and such aren't working. i keep getting an illegal function call for the PSET command

[MrPixel]

i checked the site. that's for C

well.... i guess it kind of answers your question in your other thread.

The language shouldn't matter. Just focus on the concepts. Writing a game without a state machine will result in a spaghetti mess. I can tell you that from experience

[MrPixel]

let me rephrase: how do i make a state machine in BASIC? preferably for MSX?

C is the language infants use to make games.

are you an infant?

I'm sure it's possible. If not perhaps switch to another language

have you considered posting on an MSX forum ?

because with posts like this, people on here probably aren't going to help you.

I guess most doers are infants, then.

Come to think of it, I never wrote any games in C.
The only game I wrote but was not finished was for the Apple ][, while waiting for my Uni results.
It uses High-rez mode for drawing with text on the bottom few lines for user interfacing/status text.
Moves your planes & ships using an array of 8 keys to denote the compass directions plus some other key for action.
Complete until the part of trying to figure out how the battle would be like when you find the enemy.
Since it was the early days, was done in Applesoft Basic with some assembler for sound/graphics.

I've written games in J2ME, 6502 assembler and C. I used a state machine for each. I had to make a fairly complex game front end navigable backwards and forwards on the GBA. It got unwieldy and I replaced it with a state machine. Much easier.

sorry for the post, i wasn't thinking straight. anyway, how would i implement a state machine in MSX basic? what commands would i need?

I don't know basic. You'd need a function which returns a value and a calling routine above it with a switch statement or a load of ifs.
You'd need a global which holds the current state. Depending on the value returned it would call the relevant function. A value of say -1 would mean continue calling the current function over again. The callee can switch states by returning different values. You might want to add sub states for init and finalize. This is an example in basic http://www.protonbasic.co.uk/content.ph ... e-Machines

i used to code a lot in basic on the msx, did several games on it, but don't remember any of it :'(

but try look here, this seem like a good place to find information about the MSX
https://www.msx.org/

don't know if it is something like this you are looking for

i understand how it works but i need an equivalent in Basic. otherwise, it's useless. as we have an atari 800 at school, i'll need to teach this eventually

[MrPixel]

will C basic work?
