Variables: Mixing "strings" And Actual Values, Solved: Thank you Options

[MurnaneX]

Hi im new here and I apologise if there is a topic on this already but i cant seem to find it.
I would just like to now how to do this. It will be easier with an example.
say i have 2 variables.
gun = "pistol"
pistol_ammo = 100

How would i make it so I could draw my third variable which would be
gun_ammo = gun + "_ammo"
and have it draw "100" rather than "pistol_ammo" which is what im getting now.

If this doesnt make sense just say ill try re-explain.

Thanks Murnane

You use the string function to convert real numbers to strings:

CODE

gun_ammo = gun + string(ammo);

Hmm yeah i did try that but I still got the same problem of the draw action drawing "pistol_ammo" not 100

It should work if the variables have the values you said. To double check, put the following code in the draw event:

CODE

gun = "pistol";
ammo = 100;
draw_text(x, y, gun+string(ammo));

CODE

tempvar = gun + "_ammo")
gun_ammo = real(tempvar)

I just had an idea! Try that. What your current code is doing (gun_ammo = gun + "_ammo") is creating a string, and then it draws the sting. You need to set it as a real value so it recognises it as a variable name, and then draws that.
Hope that helps!

His current code is fine. What he wants is to draw the ammo value of whatever gun he has ("pistol", "bazooka", "sniper", etc) with "_ammo" at the end.

MurnaneX: Just use this code

<Draw>

CODE

draw_text(20,20,gun + "_ammo: " + string(variable_local_get(gun + "_ammo")));

Note: You don't need the first half for your issue, just the string() part, but I thought it would be handy anyways.

EDIT: Added string(), just in-case
EDIT2: Fixed my first sentence, and added clarification to code.
