make ball move only in certain direction.

PBEmpire

i want my ball to move only at 45 or 135 degree angle if it hits slider. is this possible? when ball hits slider in my game, it moves most of the time straight.

Make an attribute called ball angle - integer

When ball overlaps or collides with slider, change attribute ball angle to (in expression editor) random(1,2)

In the ball,
Rule
when overlap or collide with slider, attribute ball angle = 1
move behavior: set the direction to 45

Rule
when overlap or collide with slider, attribute ball angle = 2
move behavior: set the direction to 135

thanks for ur help. let me try

no it did not work at all. can i send u the project file if u want to take a look? if not i will ask someone else to take a look.

Did you use the expression editor for the random? And no, I won't take a look.

ya i used expression editor. here is my attributes

When collide with paddle, change attribute- self.motion.linear velocity x to self.motion.linear velocity x +1*(self.position x-game.mouse.position x) ------ this is iphone game so i made buttons to move left or right. (I ALSO TRIED- CHANGE ATTRIBUTE TO (self.linear velocity.x)(self.maxspeed.))


When attribute-self.motion.linear velocity y > -15
self.motion.linear velocity y <-15 then, change attribute self.motion.linear velocity.y to random(70,120)*(1)^(random(1,2))

i can only move at that direction if the ball is moving at that direction. i cant change direction if it hits edge.
