Chapter 16 ■ Collision Detection: Creating SVG Polygons for the Game Actors and Writing Code to Detect Collision
Figure 16-16. Import the latest SVG data with data triplets deleted into GIMP to see curve without tension handle data
The solution to turn these non-conforming (to the sprite outline) curves into the same collision polygon that we
had before is quite simple, and you may have already guessed what it is. Since we want straight lines between our
data points, we need to change this “C” to an “L.” This will turn a curveto SVG command into a lineto SVG command.
As you can see in Figure 16-17, our collision polygon data is almost where we expected it to be, containing 16
data point pairs and a Z closing command to create a 16-sided collision polygon. We can remove the first duplicate
data pair, reducing the data set to 15 data point pairs, which is what we “laid down” in GIMP. Next, let’s again use our
Import Path work process in GIMP, and see if we get the same square polygon result that is shown in Figure 16-14.
