If you re-wrote this line in, more or less, English, what would it say?
If CountCollisions (cube) = .01 To .1 Then MoveEntity sphere,.1,0,0 Step .01
;If the number of times that the cube has Collided with something is equal to
;1/100th To 1/10th, Then move the sphere 1/10th to the right, Stepping by 1/100th
It doesn't seem to make a lot of sense, even in English. The "To" and the "Step" commands should only be used in a For...Next loop. Specifically, "To" should be used like:
For x = 1 To 100 ;Do this part 100 times. "To" is used to identify the maximum
Print "This is number " + x
Next
"Step" can be used like this:
For x = 1 To 100 Step 10 ;Do this part only ten times now because "Step" tells blitz to skip by 10's each pass
Print "This is number " + x
Next
CountCollisions() will return the number of times your entity collided with something else since the last UpdateWorld was called. You can use this number when you're looking for a specific collision point, but you have no idea before hand where or when this collision will take place. Typically, I have little use for this command, but other programmers use it quite often. Instead, I prefer to use EntityCollided() to know if my specific entity has hit another type of entity. For what you're asking, this is probably what you're looking for.
Going back to your original line of code, this is how I would write it to do the things you were wanting, including the going from point A to point B stuff. This is not a demo and will not display results in its current state. All of the code is related to the task mentioned above.
Const TYPE_CUBE = 1 ;Make a collision type for the cube
Const TYPE_TRIGGER = 2 ;Make a collision type for the trigger
Global cube = CreateCube() ;Create a cube
EntityType cube,TYPE_CUBE ;Make cube the TYPE_CUBE
Global trigger = CreateSphere() ;Create a sphere, or a 'trigger'
EntityType trigger,TYPE_TRIGGER ;Make the trigger TYPE_TRIGGER
Collisions TYPE_CUBE,TYPE_TRIGGER,2,3 ;Check for collisions between them
;MAIN LOOP HERE
While Not KeyDown(1)
;The next three lines are the way you would want to write your original line posted
