#### Using logical operators in game development Posted by Jason on November 22, 2016 at 9:55 AM Using logical operators in game development

Game development is a very complex process. It is important therefore that you get to know the best way to develop your game but choosing the right comfortable tool. If you want to develop your games, using your characters, settings, and storylines, Woodstock production can help you learn, how to use Logic operators in python.

An operator is a symbol used in the comparison of two things in any expression. For instance, in (9 > 7) the sign > is the operator. There are varied types of operators and for expressions, these binary operators exist:

- && which means "and" example "if(pi=3.14 && 4+3=7)"

- || implies "or" example "if(x=0 || y=0)"

- ^^ means "xor". example "if(x=32 ^^ y=27)"

- < "less than."

- > "greater than."

- <= "less than or equal to."

- >= "greater than or equal to."

- ! "Not." For example "if !(Variable=5)"

Operators are the constructs that can manipulate the value of operands. In the case of the expression 4 + 3, = 7, 4 and 3 the operands and + is the operator.

Operators in Python language are categorized into; Bitwise Operators, Arithmetic Operators, Assignment Operators, Membership Operators, Comparison (Relational) Operators, Identity Operators and Logical Operators in python.

There are three logical operators in Python language. For instance, suppose variable 'a' holds 10, and variable 'b' holds 20 then

- Logical 'AND' : op1 && op2

If both the operands are true, then this condition becomes true. (a and b) is true.

- Logical 'OR': op1 || op2

If any of the two are not zero, then the condition becomes true. (a or b) is true.

- Logical 'NOT':!op1

It reverses the logical state of the operand. Not (a and b) is false

Most programs generally execute one statement following another statement repeating the same process each time they are run. It is a great way to learn C++ programming, though it cannot be applied to the programming of games. The most vital tool for building this concept is the C++ if-else statement, which programmers have to understand logical operators to use Logical operators are pretty straightforward. In fact, you have seen them before in your math classes in school.

Logical operators are primarily used in controlling program flow. They are generally found part of an if, a while, or any other control statement.

The concept of logical operators is quite straightforward. Logical operators allow a program to make decisions based on multiple conditions presented to them. Each operand is considered a unique condition that can be assessed to a true or false value. When the answer to these is found, the given value of the conditions determines the overall operator value of the op1 and operator op2 or !op1 grouping.

The && operator helps determine whether both operands and conditions are found to be true and.pl. If either of the two conditions is found false, then the print command will be bypassed.

The || operator helps to determine whether any of the conditions is true.

For example:

If (\$firstVar == 9 || \$firstVar == 10) {

Print ("Error!");

If any of the conditions comes true, the print command will be run.

Caution should be taken not to evaluate the second operand if the first operand of the || operator evaluates to be true. When that is done, it becomes a source of bugs. The ! Operator is applied in converting true values to false and false values to true. The operator inverts a value.

Logical operators are normally used with Boolean values. When they are applied to an operand, they give back a Boolean value. Conversely, the && and || operators will, in fact, return the value of one of the specified operands, therefore if used with non-Boolean values, they may bring back non-Boolean value.

A value converted to true called 'truthy.' False conversions are called 'falsy.'

Even though the && and || operators are compatible with non-Boolean values, they are still well thought-out Boolean operators because their return values can be changed to Boolean values.

As they are evaluated, logical expressions are tested for any possible "short-circuit" evaluation using two rules:

- False && (anything) is a short-circuit evaluated to false.

- True || (anything) is a short-circuit evaluated to true.

Rules of logic guarantee that the evaluations are constantly correct. The anything part of the expressions is not evaluated, to avoid the effects of doing so like bugs. Furthermore, note that the anything part is any single logical expression.

Using logic operators in game development can be a very exciting venture if you understand how they to operate. If interested then Woodstock production would be the best place to start your lessons.
