you definitely don't want to drill into the brick. Drilling into the mortar isn't too bad though, and easily repairable if ever desired. 

I've used Tapcons for anchoring into mortar. They work well:



The box will say what size masonry drill bit you need to pre-drill, then you just screw them in with your driver like any screw. I'd suggest longer is better (though no longer than the width of the brick, as that may be as thick as the brick is.)

Also, make sure this brick you are drilling into isn't a chimney. If it is, make sure it's either not in use, or has a metal flu inside (and don't puncture the flu)

Your idea of installing a wood cross-member into the brick and then hang something from there isn't a bad idea.  I'd suggest 3 screws, then perhaps attach peg board to that, hanging the pots from peg board ala Julia Child



How can I hang pots on my brick wall with the least amount of drilling?
This may be a "best way to" question, so may be susceptible to opinion-based answers (which is ok for me). But I would also like if there are any tutorials , research papers , etc.

I'm trying to make a 3D free kick game, and I want to decide on the Goalkeeper algorithm.

Usually (and in my game) the shot is a function of direction , power and swerve. Maybe wind can be a factor too. So the shots trajectory is pre-deterministic, i.e., the point that intersects the goal (or out) plane is determined as soon as the shot fires.

So what could be a good approach for the goalkeeper to jump (or walk) ?

I have two approaches in mind :

1- determine the point, and jump to there. 
2- when the ball is closer than a threshold distance, estimate the point by the ball's velocity vector, and jump to there.

The problem with the first approach is, goalkeeper will always save the shot, which I want to prevent. So there should be some kind of randomness, or the goalkeeper's ability to jump and walk will be restricted.

The problem with the second approach is, when there is a high amount of swerve, the goalkeeper will always fail to save the shot.

So how could these approaches be better?

Thanks for any help !
