Please help me create this program I have done with the steps of moving rectangle up and down . Just confused with using spacebar for starting and stopping it.
The Space Bar could switch a boolean variable named moving to true or false.
Set the variable
if(key==' ') moving = ! moving; // The "!" means "not", so we toggle moving here
Evaluate the variable
Then evaluate this variable moving to move the rectangle or not :
if(moving) y = y + 3;
Declare the variable
before setup() say:
thanks it really helped:))
