speed and random item

so, i�m making an "arkanoid" game, and i wanted the ball to gain more speed each time it colides with the player, also each time it colides with an object it may or may not drop an item, how can i do this?

1st objective: each time the ball colides with player increase ball speed

2nd objective: each time the ball colides with another object it may drop or not a item.

*sorry for my bad english

what behaviour are you using for the ball ?

If you are using bullet, you can increase max speed on every desired collision.

event: ball on collision with player

action: set ball bullet speed to bullet speed + 0.01 (or whatever)

you can manipulate the behaviours speed and acceleration this way easily.

ball on collision with player: set bullet speed - bullet.speed+10

Give the blocks a ChooseSpawn variable

ball on collission with block - block set variable ChooseSpawn - choose(0,0,0,1)

• block compare variable Choosspawn = 1 - block spawn
• - block destroy

this way there is a 25% chance the block will spawn. To spawn different items you could use more numbers than 0 and 1 and spawn accordingly

wouldn't

on collision with block

and

random(100)<25

be better ?

performance wise the choose is a lot lighter.

Random also does decimals >_>

I was already planning one question ahead. Changing this event to one that spawns different objects with different probabilities is pretty easy.

There's often no such thing as better, just preferences and I like the choose option for it's adaptibility..

Thanks or that - I use random() quite a bit, time for a change.

I use the choose a lot ... if I have some event, which can give a text something, I always add something like   set text choose('hello','hi','welcome','go away')    :)

im still learning construct, so, i have the bullet effect, but i cant use the "+0.01" speed thing you said, how do i write it so it can work?

i am only putting the +"0.01" there and its not accepting the +

hmm, i understand the logic but i dont understand the making of... can you send me prints, or maybe a capx so i can see?

have you seen
