how do you make one actor not affected by gravity?

edited November -1 in Working with GS (Mac)
so i an using gravity to make blocks and the actor fall, but when i put in a background image like a cloud that also falls with the other actors (and i want the cloud to be mobile moving across) thats why i don't uncheck movable.

    Apply a gravity (acceleration) at 270º only for the actors you want affected by gravity :)

    ok, thanks!
  • snowstormsnowstorm Member Posts: 51
    ok, so now i have a problem where the actor and blocks are are turning on their side and since i put the acceleration to down they are going all over the place. and i've tried this before but i keep geting the same problem.

    Actor Attribute:

    Physics
    Fixed Rotation - Specify whether or not the actor rotates when it collides with other actors in the scene

    you would just check it, right. because when i did that nothing happend
  • snowstormsnowstorm Member Posts: 51
    or would you create a whole new atribute?
  • mangaroomangaroo Member Posts: 419
    You would check it - make sure that the prototype and actor are linked or you are ticking the actor and not the prototype
  • snowstormsnowstorm Member Posts: 51
    i'm sure, it is the orignal
  • mangaroomangaroo Member Posts: 419
    Even rules wouldn't affect it if it was ticked im sure - so double check by clicking on the blocks in the scene itself and i think if they are already on the scene then try ticking their checkbox and see if it makes a difference?
  • snowstormsnowstorm Member Posts: 51
    but when i do that they are stuck and will only fall if there is nothing under them.

    When you untick rotate the blocks stop moving? i think you've lost me here...

    usually objects only get blocked by other objects if you have set them to collide with eachother...

    make sure your accelerate down rule is relative to scene and not actor
  • snowstormsnowstorm Member Posts: 51
    it won't fall unless there is no other block touching it
  • mangaroomangaroo Member Posts: 419
    Try what JohnPapiomitis suggested that should make them more likely to fall straight down even if they bump into each other

    If you don't want the blocks to stack - disable collision of blocks with blocks - if that is already the case and u mean side-touching perhaps there is an unkempt rule somewhere disabling/limiting motion when a block overlaps with a block?
  • snowstormsnowstorm Member Posts: 51
    yah now i'm getting the thing where the plocks fly all over the place because i unchecked fixed rotation
  • mangaroomangaroo Member Posts: 419
    Ok i mean check fixed rotation and make sure gravity/acceleration for the blocks is acting 270° in relation to the scene..

    once that is done you get the problem with them stacking - are the blocks set to collide with eachother?

    Make sure moveable is still checked - only fixed rotation off
  • snowstormsnowstorm Member Posts: 51
    ok, should i have fixed rotation checked or unchecked?
  • mangaroomangaroo Member Posts: 419
    It all depends on what you're trying to make! If you don't want them to rotate untick it :) if you dont mind - leave it ticked

    And sorry in the previous post when i said check fixed rotation - meant tick since its not the effect you want :)
  • snowstormsnowstorm Member Posts: 51
    either way, they still rotate and go off to the side
  • mangaroomangaroo Member Posts: 419
    Do the blocks spawn or are they already there? If they spawn then you need to untick rotate in the prototype.
    If they are already on scene/hidden on scene check the block actors themselves...Sorry we seem to be going in circles but other than having a look at the template this is what follows...in my mind anyway!
  • snowstormsnowstorm Member Posts: 51
    they are on scene
  • snowstormsnowstorm Member Posts: 51
    so in the prototype it should be checked, but in the individual blocks it should be unchecked, right?
  • mangaroomangaroo Member Posts: 419
    its best to untick them all for now to test whats going on - especially if in the process some became unlinked from the prototype. alternatively just untick the prototype and re-drag them onto the scene
  • snowstormsnowstorm Member Posts: 51
    ok they're all unchecked, and i'm getting the thing where they fly over to the side

    Make sure the accelerate is relative to scene.
  • snowstormsnowstorm Member Posts: 51
    they're all relative to the scene
  • snowstormsnowstorm Member Posts: 51
    i have to go, but thanks for all the help! i'll come to this forum tomorrow and see if we can work this thing out. again, you were a great help, thanks a lot!

    Set the restitution under Physics to 0 or a number you are comfortable with after a little experimenting.
    Warning There was an error rendering this rich post.

    Change Attribute: Self.Rotation to 0. If it keeps rotating your file is corrupt or something.
  • snowstormsnowstorm Member Posts: 51
    i did the change attribute just now and it did nothing
