“Some witty game quote here”

Repetition & Real-time Simulations

Soon we’ll switch software simulations, but

this time we’ll reuse our familiar SpaceSmasher environment

Demo

SpaceSmasher V2

Understanding & practice with:

A Single While Loop A Single For Loop Translating For Loops to While Loops

And vice-versa TBAWhile Loops with Multiple ConditionsTBA

<booleanExpressionA> && <booleanExpressionB> <booleanExpressionA> || <booleanExpressionB>

Nesting loops inside loops with For Mixing nested For and While Loops

Lab Goals & Outcomes

SpaceSmasher is a complex but exciting environment!

Outcomes are similar to a typical CS1 class, but with different: Pros

Examples Content Motivation

Cons Setup Length Complexity

Game Lab Pros & Cons

An even more fully-featured SpaceSmasher

game When compared to the if statement lab

The first step is to read the lab We’ll start together on TODO1

Sequential Loops Flowchart

Sequential Loops Flowchart

• Loops here are not logically related to one another• In other words, they’re not nested or

related in any way• If one loop fails to execute due to the loop

condition evaluating to false, this affects no other loops

• A set of loops that each must be evaluated• And if one is skipped, this has no bearing

on the other loops.• Contrast this behavior to Nested Loops

Loops Inside Loops (Nested)

Also called Nested

Loops for(…) { //outer loop

//outer loop code //which includes //an inner loop for(…) { //inner loop //inner loop code }

}

Loops Inside Loops (Nested)

Note that if the outer loop’s condition is initially false: You never do any part of the

outer loop, including the inner loop!

INSERT CLICKER QUESTION

• TBAWhich of the following are true regarding Sequential IFs?

• Which of the following are true regarding Chained IF/ELSEs?

Single, Sequential Loops Versus Nested Loops

Paddles don’t work

No keyboard support for movement No mouse support for movement

Spawning only No collision support They do change when an upgrade block is hit

Balls don’t work They pass right through the paddle They don’t change with the paddle

To an IceBall or FireBall

TBAIn The Beginning…

First, we’ll add keyboard support

This should spawn balls just like the left mouse button (TODO1 Single IF)

And, the left and right keys should move the paddle (TODO2 Single IF)

Then, we’ll add mouse support for left & right (TODO3 Chained IF)

Next, we’ll fix the issue regarding paddle and ball collisions (TODO 0)

TBALab Activities

We’ll refactor some existing code using &&

(TODO4) To make it shorter and clearer

Then reduce a different code segment using || (TODO5)

Finally, we’ll fix the ball so it turns to an IceBall if the paddle is ice (TODO6)** And a FireBall if the paddle is fire

Lab Activities Continued

Variables & Methods

An even more complete SpaceSmasher

experience

Start by reading the lab We’ll start together on TODO1 in 10 minutes

Look at the EXAMPLES for code samples

At the End…

Once the lab is complete, look at the

assignment. What about a version of this game that TBA Or, what about a version of this game that TBA
