Simple question about OR statements

[Pixelthief]

Be prepared for the fact that a

"X not overlapping Y"

condition will always return *false* if no objects of the latter (Y) type exist, which may make your code fail to work. For example, if you have a "Player is not overlapping a Goomba" condition, but no goombas exist, then logically it would return always false- the same as if you *were* overlapping a goomba.


Just consider that and work around it logically. An easy workaround is to have a minimum of 1 of the object type on your frame, deactive, somewhere at all times

Or a condition to check for more than 0 goombas.

well I mean, if you want a generic event, like this:


"If Mario Lands on the Ground"
+
"Mario is NOT overlapping a Goomba"
+
"Mario is NOT overlapping a Spike Trap"
+
"Mario is NOT overlapping a Lava"


The event would never be able to work in a single event (sans "or" conditions) without malfunctioning when you don't have at least 1 goomba, 1 spike trap and 1 lava. Mario would never be able to land on the ground when all goombas were dead

I see your point, Pixelcrook. I guess it is easier to just add them to a qualifier and have a dummy object outside the frame also in the qualifier?

the *best* way to do it is to code around it by having it across multiple statements. Use false positives flags that tell you when you're overlapping the object
