C# Problem with ShowHelpMessage function

andre500

I'm making a mod that imports the new weapon wheel features from GTA Online.

https://www.gta5-mods.com/scripts/extended-weapon-wheel-snacks-and-armor-as-in-gta-online

I want to display the same help message with the UI.ShowHelpMessage function, but the text doesn't fit all the way in and gets cut off somewhere in the middle.

UI.ShowHelpMessage("Press ~INPUT_DROP_AMMO~ to drop ammo.~n~Press ~INPUT_DROP_WEAPON~ to drop weapon.~n~Press ~INPUT_EAT_SNACK~ to eat a snack.~n~Press ~INPUT_USE_ARMOR~ to use armor.");

Result

What am I doing wrong? How can I display a large help message?

I don't know what you're doing wrong because i"m not a programmer, so you'll have to wait for the experts. What I can tell you is that you are doing something wrong because I can get a larger message without issue. However I'm loading my message from a script which reads a text file. This allows me to reload the text or edit it rather than hard code it. Your syntax looks fine but....problem is possibly with INPUT_EAT_SNACK? Try replacing it temporarily with INPUT_DROP_AMMO and its code.

so let's see~n~how much text~n~we can put in this box~n~before it starts to truncate it~n~and then we get pissed off~n~because the message doesn't appear in its entirety.

@JohnFromGWN What script are you using? Is it open source? I'd like to see how it works.

The problem is definitely not INPUT_EAT_SNACK. I used that tag in my mod, which is already published. It works just fine.

@andre500 lol. I don't use any mod scripts. I write my own even though i'm not a programmer. But you should be able to resolve your issue. The fact that the last line is the issue is why i suggested the SNACK line.

Thank you. Your code uses the DrawText() function, which imitates ShowHelpMessage. With its help all the text is placed.

I will use it
