How to make things stick to each other?

BranFlizGames

I am trying to make it where when you press the "L" key the trailer will be attached to the truck cab. I do i do this?

liamo

in the truck actor

constrain attribute truck x (real) to self position x
constrain attribute truck y (real) to self position y

in the trailer actor

when key l is down
constrain attribute self position x to truck x
constrain attribute self position y to truck y

if you want the trailer to rotate with the truck:

in the truck actor

constrain attribute truck rotation (angle) to self rotation

in the trailer actor

constrain attribute self rotation to truck rotation

Cheers
Liamo

p.s. This will make the trailer stick onto the truck completely, to make it off to the sides, in the constrain attribute expression editor say.
self position x+your value.

PSS. you might not need the constrains for the 'Y'

It didnt make it stick to the truck..it just moved it over the truck

BranFlizGames

That didnt work..can anyone else help?

Hiya BranFliz, take a look at the below vid. Might be what you need

Hey BranFliz, liamo was correct in one way, but when doing this...
constrain attribute self position x to truck x
it should be
constrain attribute self position x to truck x + (truck.size.height/2 + a little more if you need), which will refer to the end point of the truck.
