How do I make a polygon dynamic?

Hi to all. First of all Thanks for this fantastic Engine Programm. Construct2 is the best engine for a game developer!

I'm having some problem during the creation of a graph like the one in picture https://www.dropbox.com/s/80qo4kloef76q ... 1.png?dl=0 .

I have some variables x, y and I need to show if a Points is inside or outside the polygon graph. The Points 1,2 and 3 are dynamic and taked from input box. I tried canvas, polygon but the coordinates are different for cartesian and construct2 and the graph it's impossibile to show in correct way. How can I do a dynamic graph? it's possibile? I searched around the forum, but no solution! sorry for my bad English...

You can use a TiledBackground of 1x1 with the appropriate colour. Then just size the object to whatever size you want.

thanks, but for me the problem is how? Resize using the x,y of construct is different thant the cartesian x,y because if y is highter the vertice is showed down instead to the top. For example vertice 1 (100,250) is higher than (100, 350) and should be the contrary.

Just basic math. Subtract the LayoutHeight + Self.Height from your Y, assuming your Layout is the size of your graph.

I love you!!!!
