Is there any way to have a script be unused until called?

[gdiffuser]

In other words, have a script that does something but stay inactive until an event calls it? In my case, I have a script that displays enemy HP and SP but I want to make it so that it doesn't appear unless on of the characters uses the "scan" skill. Of course, if there is an easier/better way of doing a scan skill, I'm open to hearing it because I've scoured this place and can't find anything simple.

 

[Velocir_X]

simply add a if statement before the script
and have your scan skill run a common event that activates the switch thats mentioned in the if statement
no bigie

 

[gdiffuser]

I actually already tried that and it keeps giving me module errors. I even tried putting the if statement at different points in the script to stop it doing SOMETHING unless the scan switch is on. But it either still gives me an error or doesn't affect anything.

 

[Velocir_X]

what kind of error,
can you post the script,
the if statement you used?

 

[gdiffuser]

This is the script, but keep in mind that the comments were not written in english (probably Japanese) and thus are illegible now.

The if statement is:

if $game_switches[190]
(code here)
end

190 is the scan switch, activated by a common event called scan.

 

[gdiffuser]

Oh and the error is a NoMethodError, saying there there is an undefined method.

 

[Velocir_X]

for what line method etc.?
Does the error still occur without the if statement?

 

[gdiffuser]

No, without the if statement the game runs normally, but every enemy has a visible HP and SP bar on them with their name. I want this to only appear when the skill is activated.

And the error is wherever I put the if statement. I'm not to good with this stuff so I wouldn't mind knowing a good place to put it where it will work.

 

[Velocir_X]

try
if $game_switches[190] = true
I think it my be just because you had no method applied to the switch

 

[gdiffuser]

:sad: same problem. I do appreciate the help though. Any other ideas?

 

[Velocir_X]

The If statement is written wrong is all, now if I can only figure out the correct one
racks brain,
its odd because apparently the syntax has a problem with the array, yet all tuts suggest that method,
Is it that ruby won't allow if statements before class descriptions?
Try applying the if statement ($game_switches[switch_id] != true <- cleaner syntax) more locally
try putting it in front of each method

 

[Brewmeister]

Make sure there is a switch[190]. If you haven't defined that many switches, you'll get the error.

 

[gdiffuser]

Well naturally there is a switch 190 or else I wouldn't have picked it. There doesn't actually have to be that many switches though does there? Because I have several blank spaces. Is it okay that it's simply that switch that's used?

 

[Brewmeister]

No, there doesn't. I was thinking that the switch would have to be initialized in RMXP (Using the "Change Max" button in the switch dialog). After looking at Game_Switches, you don't have to do that. (my bad)

The construct you have should work.
if $game_switches[190]
should return true if the switch is on, and false if the switch is off or doesn't exist.

Ok, I took a look at the script.... What if we do this?

Line 101

@enemy_hpsp_window.visible = @battler_visible

change to:

@enemy_hpsp_window.visible = $game_switches[190]


Then, in your Scan skill, call a common event that sets switch 190 to ON

Remember to turn it back off after battle.

Be Well

 

[gdiffuser]

Yes! It works perfectly! Thanks so much!
