deleting a string with draw_text command using switches

[Hairdude]

i'm using:-

self.contents.draw_text(200, 2, 320, 32, "test string")

basically that line appears when switch 28 is activated on a separate window.

how would i make that string disappear/delete when another different switch is activated?

Thanks.

If I understand your question correctly, use this:

if $game_switches[[color=red]i[/color]]
  # text when switch is on
elsif $game_switches[[color=red]i[/color]]
  # text when other switch is on
end

Replace "i" with the switch number.

Hi, thanks for reply

I tried that and it doesn't delete the first line of text (or even print the second line of text) when the second switch is activated

any other ideas?

Be sure to refresh the window after changing the switch.

Did you add the draw_text lines where the comments are?

 

[Hairdude]

yes i did.

I've just worked out another way of doing it, which works
but is going to be awkward when the player has loads of quests.

but thanks for your help

I've posted the code incase you wanted to look at it or use it.

In a situation like this where you need to change the contents of a window during it's updates, you should use self.contents.clear to clean the window. You then draw all the neccessary strings on. This prevents the same string from being drawn over and over again, which causes the transparent parts of the letter to build up and look ugly :-/

By the way, you do not need to use == true in Ruby. Any object that is not nil or false is evaluated as true. a == b is simply a method that examines a and b and checks if they are the same, returning either true or false:

a = 1
b = 1
print a == b [color=green]# returns true

# this:[/color]
x = true
y = false
if x == true and y == false
  print "x = true & y = false"
end
[color=green]# is the same as this:[/color]
if x and !y
  print "x = true & y = false"
end

In the example with x and y, x == true compares true to true. As they are they same, the method returns true. When both the == methods and the and method have all been run, you are left with either true or false. So when dealing with objects that are either true or false anyway, there is no need to compare them with ==. In the second example, x does not need to be evaluated so it is left as it is. The !y method takes y and reverses it:

p = true
print !p [color=green]# prints false[/color]

q = "Hello"
print !q [color=green]# prints false: "Hello" is evaluated as true, and then reversed to false[/color]
