How do I change the size of text after spawning it?

Have a system access the TextStyle component of your text and there is a font_size property on the text style that may be changed

zinc socket
#

I know that but I can't figure out the syntax

#

For example, I changed the position of the text by doing this:

fn exit_death_screen(
    mut score_style_query: Query<&mut Style, With<ScoreText>>
) {
    for mut score in score_style_query.iter_mut() {
        score.position.top.try_add_assign(Val::Px(300.0)).ok();
        score.position.left.try_add_assign(Val::Px(250.0)).ok();
    }
}
#

I can't figure out the syntax for the text size though.

#

could you try score.font_size += 300.0

#

i think you may be looking at the wrong variables on style

#

also it is TextStyle not Style

zinc socket
#

Thats weird cuz Style works just fine

#

I am gonna try your suggestion in a few minutes

#

score.font_size += 300 doesn't work

#

Also TextStyle doesn't work

#

it should be Style

fair vault
#

Style is for the ui Node that contains the Text and TextStyle is for the actual text itself

#

Also, TextStyle is not a component

#

it's in a Text section

#

so you'd need to query for Text and then do something like text.sections[0].font_size

#

or something close to that

zinc socket
#

I understand.

#

So it should be something like this:

fn exit_death_screen(
    mut commands: Commands,
    mut score_style_query: Query<&mut Style, With<ScoreText>>,
    mut score_text_query: Query<&mut Text, With<ScoreText>>
) {

    for mut score_style in score_style_query.iter_mut() {

        score_style.position.top.try_add_assign(Val::Px(500.0)).ok();
        score_style.position.left.try_add_assign(Val::Px(550.0)).ok();
        
    }

    
    for mut score_text in score_text_query.iter_mut() {

        score_text.sections[0].font_size
        
    }
}
#

I can't figure out the syntax though

#

it says ''no field font_size"

fair vault
#

should be sections[0].style.font_size I think

zinc socket
#

that could work but then how do I set the font size

#

score_text.sections[0].style.font_size(Val::Px(500));

#

could this work

fair vault
#

also, you could do it in one query

fn exit_death_screen(
    mut commands: Commands,
    mut score_style_query: Query<(&mut Style, &mut Text), With<ScoreText>>,
) {
    for (mut score_style, mut text) in score_style_query.iter_mut() {
        score_style.position.top.try_add_assign(Val::Px(500.0)).ok();
        score_style.position.left.try_add_assign(Val::Px(550.0)).ok();
        text.sections[0].style.font_size = 16.0;
    }
}

I see

fair vault
#

are you using rust-analyzer? It should help you show this information

zinc socket
#

I am it just takes a while to load

fair vault
#

right, yeah, it can be pretty slow sometimes

#

Sometimes I just reload the vscode window and it seems to help

zinc socket
#

I kinda just wait for it

#

I think it should work now though

#

I'm waiting for the game to run but the analyzer says its fine

#

I didn't get an error but it didn't work

#

the text stayed the same size

#

nvm my bad

#

I think it should work

#

I had accidentally placed it in the wrong system

#

I have 2 systems which are almost identical and I had placed it in the one that wasn't running

#

It should work now, I'm waiting for the game to run

#

Yeah, it works. Thank you for the help!
