Rotating platform

Eminem

I have an actor and i want when the actor goes on the platform, if the actor goes over to the left i want it platform to swing to the left and if the actor goes to the right of the platform, then the platform swings to the right,

Anyone know how to do this?

thanks

Swing like what/how? or do you mean rotate?

You will have to make a local variable in the platform that checks on the characters X position in relation to the platforms self.Position.X

Something like if X_Position of character > self.Position.X and platform overlaps or collides with character then do X

You could make the platform variable global but then if you have more than one of the same platforms they will all move when your character goes over to the left or right.

Hi darren

i mean swinging left and right, sort of like in the game Red Balls Of Goo ( I truly enjoy your games)

But i dont fully understand what you mean, can you please be more detailed

Thanks for your help.

So when your character is on the right side of the platform you want the platform to move right?

I want the platform to tilt right

I have this in my platform template but what ya need to do is...

In the platform you want to rotate:

Add a real attribute and call it StartY

Then do change attribute StartY to self.position.Y

Then do..Constrain self.position.y to StartY (this stops it falling)

In the physics part of actor make it movable and leave fixed rotation unchecked.

I thought you meant this when i 1st read it so added it to the template.

It does nothing. inside the platform i added a real, and have constrained and changed attribute inside the platform, but what should i do to my actor thats going on to the platform?

Darren this is what im talking about

how did you do it?

UtopianGames

You have to drag a collide behavior into your character and select your platform for the character to run on top of it.

Eminem

For some reason when the actor moves left and right the platform swings but, the patform moves left and right any clue why this happens?

UtopianGames

Try constraining the X like i showed you how to do the Y.
