Geometry Helper (GH) is a plugin with many useful helper functions.
How often have you spent time trying to align your sprites, say 4 and 5 menu items in two straight lines and later rearranged them in a different manner? How to find the meeting point of two lines? These questions we face everyday can take away considerable amount of our programming time. Well, Geometry_Helper can help you solve some of those.
Suppose you need to arrange 3 bees around a Snail. That is not very bad. How about arranging 37 of them? G.H. relieves you from all the mathematical computations for achieving this using a standard two step process. 1) Set Up the function. 2) Get the points by passing only the position numbers 1 through 37.!
Code for Setting Up GH is very easy, with minimal learning curve.
Now when you are close to the release, your design engineer says it will be better to have 39 bees and not 37. Oops! Now you will have to make so many changes and test everything again..??..!! NO!! Just change the 37 in the Set Up and make it 39. One line of change and that is all..!!
Particularly when you are trying to design screens for supporting multiple screen sizes, Geometry Helper can save you hours of hard work.
I will keep adding new functions to GH in future, as and when I get same request from considerable number of people. Or I will keep updating the sample capx to show how a requested scenario can be achieved using GH.
Please read FAQ!

It's a plugin with a few functions to solve Geometry questions when arranging items on the screen. It can be very time saving when trying to precisely arrange items on the screen.
1. Point functions to find a Point at certain distance ratio from two given Points. This is mostly intended to make you familiar with the format used for setting up GH and get the intended X,Y coordinates.
2. Given two lines, find the cross-over point
3. Arrange N number of items in a line, given a reference point at given distance from each other.
4. Arrange N number of items between two given points.
5. Arrange N items in an ARC, given the centre and a reference point.
6. Arrange N items in an ARC, given the centre and a reference Angle.
7. Arrange N items between two reference angles.
8. Polygon of N sides with given length of a side.
9. Polygon of N sides with Outer radius given.
10. Polygon of N sides with Inner radius given.
For an arrangement, you can specify some of the below settings. Please note that some settings can not be grouped together. For example, a Polygon of 20 sides with outer radius 200 can NOT have it's side as 1000 etc/
1. Number of items
2. Distance between items
3. Tilt the arrangement by certain angle
4. Align At a point (Both sides to the point)
5. Align From a point.
6. Align To a point.
7. Radius (Distance from Centre)
Using GH is a simple two step process.
1) Set Up GH
2) Get the coordinates by passing position Numbers.
Each function is identified by a Set Number, such as Set 2A, Set 4C etc. You need to use this for correctly matching the expressions for X,Y coordinates with the function being used.
Here is an example. Let's say, you need to get the coordinates of a polygon with 21 sides around the point (100,100). Also, you want each item to be 100 pixels away from the next. So, first you will invoke the corresponding action like so..
"Set 4.A Set up a polygon centred at (100,100) with 21 vertices with length of side 50 and initial offset 0.
Now, to get the X and Y coordinates of the 7th element, use the expression
You can do this in a loop too.

If you purchase an asset an an exclusive price, you are also bound by all terms in this License (c). An exclusive price means that the item from that point onwards will be delisted from the Scirra store and no longer for sale. Non exclusive licenses may have already been sold up to that point. Use the sales figures published on the items page for indication of how many have been sold to date. Licensed Content purchased at an exclusive price are permitted for use on unlimited projects within the terms of this Agreement.
If you receive a refund for payment of Licensed Content in part or full that you requested, your license is terminated with immediate effect and you must follow all termination procedures listed in (c3).

Buy this item at the exclusive price today and it we will be de-listed from the Scirra store immediately!
Items with exclusive prices are not sold anywhere else, and will not be sold anywhere else ever again if purchased at this price.
This item has currently been sold an estimated 7 times to date. Buy at the exclusive price today and no one else will be able to buy it.
I can't wait to implement this plugin in one of my projects. When I needed help I got a fast a courteous reply.
