Reset restrainer?

[satyrsfaction]

I'm working on a game, and i want the player to be able to switch characters using the select switch. it changes the characters at lightning speed instead of one at a time. I tried using the reset restrainer, i don't know if I'm doing something wrong or if thats not what I should be using. any suggestions?

The basic concept is either using bit operators as an on/off switch or you can use labels. You can use labels if you're not wanting to use bits, for instance:

mainloop

 blah
 blahblah

if switchselect then goto _restrainer

 goto mainloop

_restrainer

if !switchselect then goto _blahblahblah

 goto _restrainer

That's the basic concept, it jumps to the restrainer routine then jumps to whatever routine you're wanting when the switch is released.

OK, this is what I did -- and its still switching heroes too fast... what am I doing wrong?

 

 

if switchselect then goto _restrainer

 

goto sprites

 

_restrainer

if !switchreset then gosub _switchhero : goto sprites

goto _restrainer

 

_switchhero

t = t + 1 : if t > var7 then t = 1 : gosub _sound2 bank5

return

Ok so if your condition is in the maingameloop you will want to skip the routine unless the condition is met. So as an example something like this:

 if switchselect then goto _restrainer else goto _skpblah
 
 goto sprites
 
_restrainer
 if !switchreset then gosub _switchhero : goto sprites
 goto _restrainer
 
_skpblah

_switchhero
 t = t + 1 : if t > var7 then t = 1 : gosub _sound2 bank5
 return 

I dont know exactly how your program is written so im taking a guess of whats going on

Have you looked at the example program on the bB page?

presumably you want to switch characters the first time you see the switch is pressed and ignore it if it's still pressed

ie you need to remember the switch state from last time and then change characters only if it wasn't pressed last time

and is pressed this time.

 

something like this

 

  if switchselect && enable then gosub change_character
  if switchselect then enable = 0 else enable = 1

that worked perfectly! thanks.

I you want to search for it, the technical term for this kind of input treatment is 'debouncing'.

We switched to "Repetition Restrainer" in 2013. More info:
