Hi again… 
There are 2 things (again) I want to ask…
How do I flip object that is upside down…
Like in Need For Speed, if the car is upside down, all I need to do is just to press a button, and the car is back to the normal position…
How do I show score?
For example, A collides B, and B disappears…
And then, A’s point is added by 5…
Thank you…
for the first question select the car on frame 1 press i and select rotation then go to frame to and press i and select rotation then go to the logic bricks make a keyboard sensor set it to space lets say then make an and controller and then make an actuator select po and then select play set start to 1 and end to 2. if you want to make ut really good go to the animation editor go to the ipo box and select one of the coloured box try deleting it and press play if it doesnt work press ctrl+z and try deleting a different one im telling you this cause this will make that when the car flips and you press the button it will flip back on the wheels but the angle that you where pointing at will stay the same eg if you dont do this last part you might turn the wrong direction then u should be goin
for the second question yesterday i explained to you about the hero and the villian this time you set it up the same but now you select the vilian and give him a property named point set it to float select the hero give the hero a property of score set it to float and press the D beside it add a collison sensor and type in point link it to an and controller and link that to an actuator set it to property and then to add and type in score and under that 5
Ok, I’ll try…
About the score, it’s not shown on the screen…
I already pressed the D (Print debug info), but it’s not printed…
are you using 24.9 b secondly did you set it to float
Yup, I’m using Blender 2.49b
I think I’ve found the answer…
But, anyway, thank you so much for your help… Especially for my question no 1…
