Sliding Puzzle (3x3) Definition AFRLme

This script is used to generate & control a randomized sliding puzzle consisting of a 3x3 grid. Visionaire Studio 4.1+ is required to run this script.

Instructions

1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2a. First thing you should do is update the t[1] to t[9] tables with the correct x, y positions for where each tile should be placed (top left pixel).

 t[1] = { .. x = 288, y = 221

2b. Next you should define where each tile is allowed to slide to in the move section of each of the tables. See the diagram below for an explanation of how I determined which tiles can move where.

t[1] = { .. move = {2,4} -- grid position 1
t[2] = { .. move = {1,3,5} } -- grid position 2
t[3] = { .. move = {2,6} } -- grid position 3
t[4] = { .. move = {1,5,7} } -- grid position 4
t[5] = { .. move = {2,4,6,8} } -- grid position 5
t[6] = { .. move = {3,5,9} } -- grid position 6
t[7] = { .. move = {4,8} } -- grid position 7
t[8] = { .. move = {5,7,9} } -- grid position 8
t[9] = { .. move = {6,8} } -- grid position 9

3. Next you need to edit the animation names inside of the n table. All names should be the same but with a prefix number on the end. Any changes you make here will have to be changed inside of the puzzleState function.

n = { "anim_p1", "anim_p2", "anim_p3", "anim_p4", "anim_p5", "anim_p6", "anim_p7", "anim_p8" }

4. Create a condition called puzzle_solved, this will be used to determine if puzzle has been solved & whether or not you can move the tiles.
5. To check if a tile slot is empty or whether tile can be moved you should create an execute a script action inside of a left click (immediate) action containing...

canMove(i) -- replace i with the tile slot number.

6. Finally you should create a called by other action inside of the scene actions of the scene where the puzzle is located. Name it act_puzzle_solved & inside of this action add the actions that should be triggered when the puzzle is solved.
