  n X Pressed

  Object - Pick instance with UID NewArray.Back

  -Pop back on X axis

  This should work, are you setting up the array with object UIDs?

  If you measure how much the player moves then you can move everything, including the player, by the same amount in the opposite direction. Another way would be to make the layout unbounded and use the scrollto behavior on the player.

  an anyone give some practical examples, how to use local vars effectively?

  They are handy for temporarily storing values from one event to another. The key word being "temporary".

  hy is it not possible to assign a default value to some parameter like Sprite.X?he values of the first instance of a sprite is where the initial values come from.

  You can use the wallclocktime expression to measure the time passed. It's unaffected by the fps.

  global number end_time

  start of layout:

  -set end_time to wallclocktime+30

  end_time <= wallclocktime

  C2 r100 added a fix to the platform behavior so it works with vertical moving platforms. The workaround now clashes with the platform behavior so the solution is to remove the workaround.

  Sqiddster's solution works here:

  To stop the loss of momentum set the deceleration to 0 when you jump and back to what it was before when you land.

  It's different in r103 because a bug fix of this issue:

  http://www.scirra.com/forum/top-level-event-bug_topic56490.html?KW=

  As it is now I think it's a very logical behavior as events are evaluated from the top down.

  If you don't want the circle to be clicked you can change the order of the events.

  You could use the Sprite.PickedCount expression with the system compare condition to see how many are picked.

  Those conditions work flawlessly for me. What other events are you using?

  They do work in the same event but you need to change the order to

  "compare instance variable" then "pick random instance".

  You can emulate key presses with the "simulate control" action for the platform and 8direction behaviors. For general simulating mouse and keyboard controls I would set some state variables for each control and use the variables in my events instead of the mouse or keyboard conditions. Then simulating a control would be as simple as setting a variable.

  I don't think simulating the controls would give an exact replay unless the game ran at the exact same framerate the whole time.

  If you want just a visual playback then the game state is unimportant. You just need to save the position,angle,size,opacity or anything that can change visually for each object on screen every frame.

  hoanganh17 you say it's for game testing, could you give an example where it would be useful for testing?

  Images are saved to spritesheets to save VRAM in C2:

  Music and sounds likely take the same amount of space as their file sizes. There is no need to fully decompress an audio file in memory. Only the bits of the sound that will be played soon are decompressed and sent to the sound card to be played.

  The 0:7 is the column:row in th .fx file of the error and "No precision specified for (float)" is the error.

  I found this page that seems relevant:

  http://learningwebgl.com/blog/?p=2507

  Add this line to the top of your shader and it won't assert.

  precision mediump float;

  Hope that helps, from best I can tell this is a subtle difference between webgl glsl and opengl glsl.

  Here is a capx of the methods I wrote about:

  I personally like the instance variable solution, it's very clean.
