Problem with making things go behind others in animations

[nosnarbo]

What is it you are trying to achieve?
I am trying to make a bug fly behind a frog on the edge of the screen in an animation, making it look like it's getting eaten.


What is the problem you are having?
I am doing this for a school assignment and the teacher restricted the use of refreshing the frog. She says there is a way to do it even without refreshing, but no matter how hard i try, i can't seem to get anything to work.


Describe what you have tried to solve this problem
I've tried shrinking the bug, covering the bug and deleting the bug at the time of contact with the frog. Nothing seems to work that well.


Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)
I'm trying to make this

Turing:

for x : 0 .. 700         drawfillbox (-26 + x, 313, 40 + x, 375, 115) %fly erase         drawfillarc (-5 + x, 340, 10, 30 - x div 10, 0, 180, 0) %fly wing left         drawarc (-5 + x, 340, 10, 30 - x div 10, 0, 180, 7) %fly wing left border         drawfilloval (0 + x, 328, 25, 15, 7) %fly body         drawfillarc (5 + x, 340, 10, 30 - x div 10, 0, 180, 0) %fly wing right         drawarc (5 + x, 340, 10, 30 - x div 10, 0, 180, 7) %fly wing right border         drawfilloval (10 + x, 330, 5, 5, 0) %fly eye         drawfillarc (630, 345, 43, 40, 238, 129, 48) %frog4         drawfilloval (630, 375, 5, 5, 7) %frog4 eye         delay (7)     end for

go behind this:
[syntax="turing"]
for x : 0 .. 45
drawoval (640, 345, 50, x, 48) %frog4
end for
[syntax]

Please specify what version of Turing you are using
I'm using Turing 4.0.5

well you could just check the spot where you drawing and whether it would draw over the frog.

i'm not sure what you mean by that. sorry i screwed up typing the ending syntax tag for the second part of the code.

but if i draw over the frog using the bug, it would leave a trail, cutting through the frog.

do you know about if statements yet?
