[SOLVED] How to tint a label? (and change opacity in runtime)

[Ragetto]

Hi!

I’d like to tint a label (to change the opacity in runtime), but didn’t find much information except this:

https://gist.github.com/britzl/9880dad39b0d01fa0c908927320dd6d1

It’s said “DEPRECATED” but I don’t see any other way to do it, so… I followed the instructions:

After assigning the material in question to my label, the game crashes and I get a rain of errors (probably created by the same cause):

Is it the correct way to tint my label? If so, what did I do wrong?

[Ragetto]

Just applied the small modification from there:

Tinting Labels

So, it turns out it wasn’t all that hard. Here is what I ended up with for the fragment shader: varying mediump vec2 var_texcoord0; varying lowp vec4 var_face_color; varying lowp vec4 var_outline_color; varying lowp vec4 var_shadow_color; varying lowp vec4 var_layer_mask; uniform lowp vec4 texture_size_recip; uniform lowp sampler2D texture_sampler; uniform lowp vec4 tint; // The tint applied to the material void main() { // Copied from /builtin/fonts/font.fp lowp float is_single_laye…

But it doesn’t work…

Note: when I apply the material, the label becomes transparent in the editor

Is there a workaround to control the opacity of my label?

Try this:

go.set("#label", "color.w", 0.5)

@benjames171

go.set("#label", “color.w”, 0.5)

Oh thank you it works, it was much simpler than I thought I feel a bit ashamed.

I suppose this would be the same for outline, shadow etc. (in case of more “complex” labels)

Thanks

All properties that you can manipulate at runtime on the label can be found in the manual:

Label text components in Defold

And in the API reference:
