Collision problem

[pixel4all]

hi there people i'm new to GE and i want to ask 2 simple questions :

- i'm making a arcanoid style game and i have a problem with collision.. i make some rectangle cloned blocks on which the ball actor collide and i set 2 events for bounce on them and destroy them...so the problem is that the ball sometimes go through that blocks and destroy 2 or more of them before bounce.How can i avoid that?

-i also want to know how can i change level when all those cloned blocks destoy.

SORY FOR MY BAD ENGLISH

keep on good work people and happy new year!

[jimmynewguy]

do you have this turned on?
if no do it thats the most likly problem

-i also want to know how can i change level when all those cloned blocks destoy.

Put the following script on an actor (I'd suggest the player):

Code: Select all

if(block.cloneindex < 0)   //if there aren't any blocks left
{ level = level + 1;} // increases the level variable as long as there are no blocks left

make sure you add new blocks in the same function right away, otherwise you won't stop to reach a higher level forever.
If you didn't get this, I'd be happy to make a demo for you.

and if you're making a breakout style of game, I wouldn't use physical response, I'd more like use a change of xvelocity/yvelocity, that is, in the most cases, more reliable.

to jimmynewguy : turning on "repeate this event while actor is colliding" doesn't help with collision problem

to Kalladdolf : i'll try it thx for response a demo will help anyway..

can you help me with collision prob i use "change xvelocity/yvelocity" for ball bounce and destroy actor event with collision on blocks, but sometimes ball goes through blocks before bounce...any ideas how to avoid that
i also have an other weird prob when ball collide between 2 blocks it goes through blocks

tnx u for help guys

[Kalladdolf]

All right, I just came across a demo, makslane made a very long time ago, so I didn't have to make it myself, so that takes care of that.
You'll find it here.

when i use this script :

if(block.cloneindex < 0)
{ level = level + 1;}

i can't change level because i use same blocks in other levels so my question is how can i change level when all blocks in viewport are destoyed?

--- is there any way to change a block's colour with script? i must use different sprites for blocks with different colour or can i change the colour of these blocks with script?

sorry again for by bad english...

[skydereign]

To change color, you just set the rgb variables. So if you have a white sprite for your block, in its draw actor event

Code: Select all

r=255;
g=0;
b=0;

This makes it red. You change the values accordingly.
If you are reusing the blocks then you can do this,

Code: Select all

if (ActorCount("block")==0) // if the amount of blocks is 0
{
    level++; // goes up a level
}

tnx for help skydereign but i need some more

....i want to color blocks with script but i can't change the rgb values when i use clones of a block...rgb values change color for all cloned blocks is there any way to change color seperately for each block?

thn again

[skydereign]

Yeah, it depends on when you want the color changes. You could use timers, though I would suggest a switch. This example assumes they change color by level.
tile->DrawActor->Script Editor

Code: Select all

switch(level)
{
    case 0: // this means blocks will be white if level is zero
    r=255;
    g=255;
    b=255;
    break;
    case 1: // blocks red if level 1
    r=255;
    g=0;
    b=0;
    break;
    // and so on
}

If they are supposed to change not by level, and you still need help, just ask.

[pixel4all]

to be more specific i want to do this:

i want to use a single block for every level ---> level1_block,level2_block,level3_block...

in level 1 i want to use clones of level1_block and i want to change the color of these blocks thus i have in level 1 green,blue,red or whatever color i want...

[skydereign]

The switch statement will still work. You would need to change the variable inside the () to be cloneindex. That way, your clones will be different colors.
level_1_block->DrawActor->Script Editor

Code: Select all

switch(cloneindex)
{
    case 0: // this means block.0 will be white
    r=255;
    g=255;
    b=255;
    break;
    case 1: // block.1 will be red
    r=255;
    g=0;
    b=0;
    break;
    // and so on
}

thanx for all help skydereign sorry for reply delay...i had a prob with my account ...

[pixel4all]

just an other question :

ball.actor destroy when it 's out of vision and number of lifes decrease by 1... this happen also when level change...how can i avoid life decrease at level change

[skydereign]

Not sure on the context of this, one way is to destroy the actor before that, or manage it with a variable. Or if it happens every level change, in the level change code, increase life by one. These aren't necessarily the best way, so if you want a different approach, please explain the other factors.
