Actor on moving platform help please

VGX

Hi,
I want my actor to land on a moving platform but without me having to move the actor with the platform. I want the actor to land on it when it moves and stay on it.

How do I do this? Thanks

ashtmj

if player collides with ledge constrain self motion X to the same speed the ledge is moving

VGX

Hi,
Sorry I don't understand what to do. I have tried but clearly doing something wrong. Sorry to be a pain could you give examples?
Thank you

MotherHoose

which way is the platform moving? left and right? … or up and down?

left and right … as @ashtmj said constrain X
up and down … constrain the playerActor's Y

the platform is going left to right, heres the rules in the platform,

ACCELERATE- direction 270, Acceleration 400, Relative to actor

COLLIDE- floor

CHANGE ATTRIBUTE- (self.M.L.V X) to 100

RULE- self.pos X > 400
CHANGE ATTRIBUTE- (self.M.L.V X) to -100

RULE- self.pos X < 100
CHANGE ATTRIBUTE- (self.M.L.V X) to 100

for the physics, Density is 1, Friction and Restitution is 0
Fixed Rotate and movable are both ticked

What do i change? and where do i add the constrain X?

Thanks again

gameAttribute with a real type … platformX … (only activate when collides with playerActor)

-on the platforms: Rule: when: overlap or collides with playerActor - constrainAttribute: game.platformX To: self.Position.X

-on playerActor Rule: when: overlap or collides with platform - constrainAttribute: self.Position.X To: game.platformX

then constrains are only active during overlaps/collides

Hi, Sorry to keep asking but this should be the last time. I have sorted the constrain x thing. thank you for that. but having another problem, how do i make a platform go up and down? this is the rule i have for left to right,


ACCELERATE- direction 270, Acceleration 400, Relative to actor

COLLIDE- floor

CHANGE ATTRIBUTE- (self.M.L.V X) to 100

RULE- self.pos X > 400
CHANGE ATTRIBUTE- (self.M.L.V X) to -100

RULE- self.pos X < 100
CHANGE ATTRIBUTE- (self.M.L.V X) to 100

for the physics, Density is 1, Friction and Restitution is 0
Fixed Rotate and movable are both ticked


but don't know how to do up and down, thought of changing the X to Y but that doesn't work.
thank you for your help

MotherHoose

change the X to Y and also change platform's self.Motion.Linear Velocity .Y

hooray! you got the left and right! and, now you can get the up and down!
