Shadow text

totebo · September 2016

What's the best way of creating a drop shadow for a TextField? I'm creating a new version of the TextField and set it to transparent black.

Is there a way I could do this with a shader instead? Or some other way that would be less work (for me and Gideros). Ideally it should be applicable to any Sprite.

with some shader you can probably make black and white and then blur the copy of your textfield, which would make the shadow more realistic.

Yeah! Tried RenderTarget but it wasn't as sharp as the rendered text, to it looked a bit off.

@totebo did you enable antialiasing on the rendertarget?

totebo · September 2016

Yeah, tried both true and false, similar results.

I'm currently using (like yourself) a second TextField offset by x,y values and opaque with setAlpha(). It works so I don't see any reason to change. In theory you might have 3 or 4 on screen? Any more and your'e probably in some menu or whatnot where it doesn't really matter about performance.

If you want blurry shadows, just make a second font with that blurred look and use your current method, just with the new font.

I thin it would be performing better than a shader but can't say for sure because I have not looked at shaders at all yet.

Nice one @antix, I'll leave it with dupe TextFields.

Try this:

local text_title = TextField.new(font, "shadow text")
text_title:setTextColor(0xffffff)
text_title:setShadow(2,1,0x00ff00)

@jdbc, that looks like a nice way of doing it. Do you have the class for this? My class is a Sprite with two TextFields in it.

Use gideroscodingeasy.lua and TextField extension.
