Constrained actors not moving in sync, not colliding with walls and scrolling backgrounds
I'm working on a project wherein I've created an actor, and have constrained its various body parts in order to get perfect collisions. It's working and its constrained perfectly but I have three issues, viz :
Constrained shadow (Being placed at the bottom of other parts obviously) moves with a lag when the entire actor moves.
I've set up walls on three sides of my screen, have set up collide behaviours to enable them to collide with my actor(tagged with other group of actors and parts) but still, it wouldn't collide with a few actors and would collide with others. (Half of my actor moves off the screen and only its main body collides even though other parts are set to collide as well) and yes I've also tried adding collide with walls behaviours in the actors but even that doesn't work. Also, on scrutiny, I found out that when I tick "Movable" under walls, it collides properly, but when Movable is set to off (un-ticked) it only collides partially with a few body parts only.
The most annoying issue,
I have my background scrolling infinitely (Portrait scrolling), using tricks and tips given by Jamie cross, BBEnk and others (Cheers for your extremely helpful videos guys) I've set it up perfectly and have used BBEnk's tip for Universal builds and it works wonders using camera and offset actors and using stretch while keeping the actors size intact. The issue which I face is, When I use stretch while previewing on other platforms, say on an iPhone 6 plus (Ive made the project taking iPad portrait as the base), what happens is, there is a big black belt that appears between two backgrounds when I preview on other devices (In GS Creator), This belt does not appear if I preview it normally using iPad portrait as screen.
BBEnk suggested to use a larger background but that too does not work for me.
Please help me solve these issues
Thanks and regards,
