Type mismatch

Reports GDScript variable and constant declarations that miss an explicit type hint when it can be inferred, and flags typed use of the := assignment.

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

GdCheckVarType

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | GdScript | Code checks

Notes:

Suggests adding a type when the initializer expression has a concrete, non-Variant/null type.
Ignores resource-like types that cannot be resolved precisely.
The := assignment cannot be used together with an explicit type hint. Use = when a type is specified.

Example:

var hp = 100          # suggests: var hp: int = 100
var hp: int := 100    # error: ":=" assignment cannot be typed
var hp: int = 100     # OK
