Dear all, this is part of my code. I initial all as false at first, and set it to true when certain time is reached. But when time is reached, nothing is shown in the screen except the mouse… I want the images fall down from the top one by one every 2 seconds, and want it to be disappear when it collides with the mouse… Thank you so much!!! :sob:

won’t work

Try without /1000 and then check for > 1000

I think none of your conditions are ever true. You use exact timings (millis()-startTime)/1000 == 2 but how likely it is that timer evens with 2000 when that part of code is run. Draw() cycle runs by default 60 times a second, but it’s not guarantied. So you cannot know that 120th frame would be at 2000 millis. It could be 2001 or 1999 and your test misses it. Besides comparing a float to an integer is doomed to fail. By nature of floats result of division 2000/1000 is not 2.0, but can be something very close to it like 2.0000001.
So you should test (millis()-startTime)/1000 >= 1.95 and (millis()-startTime)/1000 <= 2.05. If it still doesn’t trigger your draw you need to widen the range a bit. You can probably narrow it a lot: (1.99 and 2.01) should work.
