I need to find out how to code this correctly
from the main timeline in level 0, if you load (1.swf ) in level 1
I need (button1) on the main timeline to be hidden and not function while the swf in level 1 is playing. (will a button hidden still show the cursor?)
If (1. swf) in level 1 is NOT playing than (button1) should be visible and working.
Or I can just change the button to an mc and when the (1.swf plays) in level 1 the (mc1) should be removed
if (1. swf) in level 1 is NOT playing than (mc1) should be visible and functioning.
Still grasping the if statement and I believe this can be used here but I need help on how to code it
you'll either need to use a loop to repeatedly check if _level1 exists and, if it is, determine if its timeline is playing or use some specifics of your setup to obviate the need for the loop.
to make a button (mc1) visible (and functioning) or not visible (and not functioning) you can use:
mc1._visible = false; // or true
you can also assign its _alpha property to make it visible or not but it will always be functioning, even when not visible, if you use the _alpha property. so, it would much more typical to use the _visible property.
