Text doesn't want to be drawn together

[Lemur]

I'm trying to draw a text showing on which level of the game the player is. Variable "lvl"(on 1st level it equals 0, that's why I add 1 later on) is stored in object "obj_enemygen". I want it to draw for example: "Level: 1".

Here's the line of code I wanted to use for this:

draw_text(5,5, "Level: " + (obj_enemygen.lvl+1));

But when I get to point when it should be drawn, I get this error:

Drawing itself works, it can draw both "Level: " and "(obj_enemygen.lvl+1)" separately, it just won't draw it together.

Does any of you know why this might be happening and how to fix it?

You're trying to draw a numeric variable while the "draw_text" function is expecting a string. You can easily convert the number to a string like so:

draw_text(5,5, "Level: " + string(obj_enemygen.lvl+1));

Edit: And I should add that it works when you separate them because gamemaker does the conversion automatically. But when you use a "+" to concatenate strings, each section -must- be a string.

Thanks for fast response, works great :)

One question though, why does it work when I want to write numeric variable only?

I actually edited my original comment with the answer to that a few minutes after I posted it on Monday. It should be noted that most programming languages DO NOT convert variables automatically, so it's an important concept to be aware of for future projects.
