TRying to start a blinker in a new cog

lockadoc

I'm trying to start a blinker in a new cog ,to be used to let me see there is still life in the prop, while it does other things,
which might not happen for hours.

I've built this method by following page 81 in the PROP Manual, but I must be making an error for it will not blink the led.
Can some-one tell me what·I have·copied wrong?

Thanks BillyS

LifeCogId is initialized to 0. When you call stop you stop the cog that Spin is running in.

How do I correct that,, I don't see that in the book.



Thanks

A specific fix, not a general one, would be to change -1 to 0 in the if statement.

Have a look at different Objects. That's why they tend to use cognew() + 1.

Pub Start                                                           'Starts the new cog method
  Stop                                                              'Prevents multiple starts of this method
  LifeCogId := cognew (Life, @LifeStack)[b][color=green] + 1[/color][/b]                           'Starts and gets a cog ID
  
Pub Stop                                                            'Stops the cog that was started  
   if LifeCogId[s][color=red][b] > -1
[/b][/color][/s]    cogstop (LifecogId [b][color=green]- 1[/color][/b])
 

That's the general fix.

thanks thats what I needed.I knew it was something very easy,
But when you don't catch it at first, it looks real hard and can drive you nuts.

Thanks BillyS
