Title text component options for nicer text #29

Closed tassaron closed 7 years ago

tassaron commented 7 years ago

It would be easier to make nice-looking text on different background images if there were an option to add a stroke (outline) or drop-shadow to text. I would also like to see the ability to select extra font styles such as Small Caps, Bold, Oblique, and Italic.

In addition to text borders, it'd also be nice to be able to define the text border width.

Other suggestions for improving the text component: Give a "center" option, that keeps the text centered in the screen (based on the canvas size)

The text component should also re-calculate it's position on a canvas size change. We had discussed before about storing the position as a float and always calculate the pixel positions based on simple math at render time.

xPosition = x / width     |    x = width * xPosition
yPosition = y / height    |    y = height * yPosition

If current Canvas size is 1280x720, and text position is 640x374:

0.5 = 640 / 1280
0.519444444 = 374 / 720

If resolution chagned to 1920x1080:

960 = 1920 * 0.5
560.99999952 = 1080 * 0.519444444

And round to the closest whole pixel: x = 960 y = 561 <- equivalent positions for 1920x1080
