If I'm not mistaken something like the Text Blitter extension from MMF is already requested for Construct. And I'm really looking forward to this. But in the meantime I came up with my own workaround. I don't think it's very elegant, but works on a basic level.
Just try the cap. You can type any text inside the edit box and by clicking on the "Text it!" button it will be displayed character by character in a custom bitmap font. Well not ANY text, since I only included the letters from A-Z. Full stop, comma, exclamation mark and question mark will work as well. No other special characters, hell I didn't even include numbers so far (yes I'm lazy). But you can add any character you want quite easily. I hope my event comments are satisfactory.
If you have a better solution please let me know. I'd really like to see this being improved. I already thought that I probably should have used a single sprite with different animations or frames for all the characters, but right now I'm happy it works at all (also regarding the fact that at first I had no clue how to do this).
