i have a ball. I want to find out if this ball has hit another object. I used the code:
blockhit = object hit(2,0)
blockhit is my variable.
But as there are over 100 blocks to check through it is very slow and jerky, can anyone think of a way to check if it has hit another object? It is breakout by the way.

What you will probably have to do is store the IDs of all blocks that can be hit into an array, then just check the blocks in the array.
As blocks are removed, you will have to modify the array or generate a new array.
Not sure if this will give you any speed increase.

Have you thought of using sprites instead?

All the Best,

i tried a for loop to check all the blocks, it is still quite slow, i was thinking along the lines of only checking the blocks if it is above a certain point. That would make it fast, but then suddenly slow! thnx anyway. I wanted to make it 3D looking.

I don`t get what you are trying to do, the code you list gives you the number of the block you hit, why would you want to run the test 100 times over???, maybe a better description of the problem would help.

3D breakout, i am doing a test to find out if the ball has hit an object, and then what object it has hit. To do that I used that test. However, this was too slow because there are 100 blocks, hence the test would repeat 100 times. I am trying to find a way to do this which would make the game faster.

in the tutorials which are in the DB manual they use a differnt type of collision called 'maths collision' this is much faster than standard collision. It is in the bit where they check if th bullet is hitting the monster. Check It Out !
