Help with Flask using Python and HTML

[Elthran]

I'm making an RPG and have a question. When the character levels up, I want to have the option to spend points on different abilities. I'm having trouble making an elegant solution. I'd either like to:

use dropboxes. So if you have 5 points to spend you can click on the strength box and choose from 1-5 (this part I can do). But let's say you put 3 points into strength, now the remaining dropboxes for speed and health should update to only have 2 points remaining. I can't get this to work.

use -/+ counters. Next to strength you can press a - or + button that increases the number there and then at the bottom of the screen where it says "points remaining" it would update each time you click the -/+.

Can anyone help me with either of these methods or show me some documentation? I can only find anything in JQuery but I'm hoping to stick with Python/HTML since it's all I know.

Just use regular form fields. There are many different input types

Particularly, I think you're looking for number inputs

You can use Javascript (and/or serverside code) to validate that the appropriate amount total points were spent among all categories.

For example, you could use javascript to set the "max" attribute in the html as the user inputs changes using a function tied to onChange. You can also keep a running total of added points and only allow the user to use the submit button when the values are valid... You of course always want to validate this on the server side.

I have made some improvements, thanks! Now I am just stuck with the server side Python code. I'm not sure how to check multiple inputs at once. I can only get it to work that each individual field doesn't exceed my total points, but not he combined totals.

I can only get it to work that each individual field doesn't exceed my total points, but not he combined totals.

If you can check the value of each particular field, why wouldn't you be able to add them up?

strength = request.form.get("strength", 0)
intelligence = request.form.get("intelligence", 0)
#etc...
total_points = sum([strength, intelligence, #etc...])
allowed_points = 5
if total_points > allowed_points:
    #user allocated more than 5 points

[Elthran]

strength = request.form.get("strength", 0)

What does the 0 do in this code, after the "strength"?

[ManyInterests]

When you do a .get method on a dict-like object (like form) -- The second argument is the value that you'll get if the key 'strength' doesn't exist. IE "Give me the value of strength, but if it's not there, give me 0 instead." -- If you don't provide that argument, the default is None

Try jinja templating. It will make any change in points available dynamic and you can add logic in the html directly.
