Small problems with game..

[Brian]

Hello all,

Hope you all had a enjoyable Christmas and New Year!

Making some good progress on my Air Hockey game, which you've all
heard so much about! :)

Apologies for the vagueness of the following:

Having some little problems not... got my hit-testing working but am
having problems with it at the bottom of the table (typically) for
some reason. The puck seems to react a couple of times at the bottom.
Here's a link to my Table form (along with the Table and puck - put in
Debug folder to work!)

Could ye please have a look at it and suggest why this could be
happening?

PS - Also, i'm about to begin to implement user interaction into it.
Such as the puck reacting when the mouse enters it? How could i go
about implementing this?

Brian,

You haven't posted any code, or attached a project. It would be helpful
=)

I think that what is happening is that your puck sometimes winds up
below the bottom of the table, so far that it is two velocity-intervals
off, so that it senses it is off, reverses direction, then in the next
cycle sees it is _still_ off, reverses direction again, and - somehow;
this isn't really clear to me - finds its way back onto the table this
time. I think the root cause of this may be the discrepancy between
your "pth" region, with a boundary at 596, and your lower bound limit
of 595. Another source of problem is the diagonals of the pth
trapezoid - with respect to x position, it will be common to see it
"straddle" the boundary because the x coordinate of the boundary
changes as it moves in the y direction.

HTH,

Hello Brian. The game is coming along nicely since the last time I saw it.

In your game-draw routine, where you check for the ball position, you need
to allow the top-bottom left-right test to adjust the velocity in both
planes X and Y in a single cycle. The ball is getting stuck on the edges and
wobbling in certain circumstances. I think this is because the puck velocity
isn't 1 so the puck can travel past the edge far enough that it gets locked
in a zone where it's always off the edge and bouncing with every go round
the loop.
