CanDo General Help Thread

[lifeschool]

I thought I'd start this thread in case anyone out there wants to try out the multi-media creator CanDo.

There are quite a few things I discovered by trial and error, so if anyone wants advice or can share tips, that would be great.

Installing:
I found V3.0 on the EAB file server, or it could be on Archive.org. There may be other places like PlanetEmu etc. Once installed, run it, then quit. Then run the V3.008 update patch from Aminet.

The update patch switches off the interlaced interface, so you might want to press the Config button, Screen, Cando - and click Interlace, and Save it - to switch it back on again.

Any answers?
Also, my tutorial is for CanDo 1.x/2.x - is there one for the 3.0 version?


I still need the tutorial if anyone has it, but found the answer to my question myself.

At the end of your routine you put:

ExitScript <Return value>

Then you call the routine like this:

Return = Do "myroutine"

FYI....

This quote is from an old post. I tried to use the return command but it seems this doesn't appear in the Lexicon, and comes up with an error. I'm looking for a reliable way to loop the inputs so that the game checks for joystick inputs every few jiffies, but otherwise keeps the game rolling. I want to call the joystick function but I dont know how to do this, as the function is not a routine I can access?

I can force the game to run in a while loop, but doing so locks me out of the interface, and the buttons, so there is no way to break out of it - causing the game to lock up.


In an ideal world I would put

Wait Until Joystick Arg2<>Nothing

But I cant get my head around it.
