Coding with TGB

#1 Looks interesting. Good luck with your new project. :)

#2 Excellent start. Keep at it.. and keep us updated!

#3 Good simple idea, because half the problem with iPhone game projects is that the game is to complex...and not simple enough.

But good luck! Keep us updated

#4 Alien Abduction is a great game!

I'm curious... What's the difference between what you coded and using the built in collision system via in script?

function obstacle::onCollision(%srcObject, %dstObject, %srcRef, %dstRef, %time, %normal, %contacts, %points)
{
   %vel = %srcObject.getLinearVelocity();
}

#5 Hi Patric,

Thanks for your feedback. It looks like onCollition method is being called after objects' velocities are zeroed. For the following code:

function player::onCollision(%srcObject, %dstObject, %srcRef, %dstRef, %time, %normal, %contacts, %points)
{
	echo("%srcObject vel = " @ %srcObject.getLinearVelocity() );   
   	echo("%dstObject vel = " @ %dstObject.getLinearVelocity() );
}

I am getting:

%srcObject vel = 0.000000 0.000000
%dstObject vel = 0.000000 0.000000
%srcObject vel = 0.000000 0.000000
%dstObject vel = 0.000000 0.000000
%srcObject vel = 0.000000 0.000000
%dstObject vel = 0.000000 0.000000
%srcObject vel = 0.000000 0.000000
%dstObject vel = 0.000000 0.000000


I also remember reading somewhere on the forum, that this was exactly the case for onCollision call.

Interestingly, when I try different collision (meaning different object and different angles) I am able to get the following:

%srcObject vel = 0.000000 0.000000
%dstObject vel = 0.000000 0.000000
%srcObject vel = -6.368989 -4.773498
%dstObject vel = 0.000000 0.000000
%srcObject vel = -5.327312 -3.992772
%dstObject vel = 0.000000 0.000000
%srcObject vel = -4.572809 -3.427278
%dstObject vel = 0.000000 0.000000
%srcObject vel = -3.839827 -2.877915
%dstObject vel = 0.000000 0.000000
%srcObject vel = -3.127752 -2.344221
%dstObject vel = 0.000000 0.000000

#6 Thanks Piotr! That's a nice clean solution to the problem. I'll be following your blog.

Good luck!
