Advanced timing involves creating a game engine that functions independently of the
movie’s set frame rate
|
|
|
2.
|
Changes to the actual frame rate of the game should have little or no effect on the
speed at which things move in our games.
|
|
|
3.
|
With
onEnterFrame you are tied to the frame rate of the movie
|
|
|
4.
|
To
determine changes for _x and _y in a positoin of an object, there are two choices: trigonometric
functions or you could use vectors
|

|
A
right triangle is defined as any triangle that has one right angle, is obtuse, and is
acute.
|
|
|
6.
|
The
side that opposes the right angle in a right triangle is called the leg.
|
|
|
7.
|
A
bounding circle is were you use a circular boundary around an object to hit test
against.
|
|
|

|
The
sum of all three angles in a triangle is 270 degrees.
|
|
|
9.
|
Radians are just numbers that represent angles, like degrees.
|
|
|
10.
|
Tangent takes an angle as its argument, like sine and cosine but it returns the ratio
of the sine of that angle to the cosine of that angle
|
Multiple Choice
Identify the
letter of the choice that best completes the statement or answers the question.
|

|
To
free the game from the frame rate, we must get rid of a. | event
handlers | c. | intervals | b. | onEnterFrame | d. | none of the above | | | | |
|
|
|
12.
|
Timing is important in game programming because... a. | Timing is always
system dependent with Flash when using interval | c. | the onEnterFrame event handler will update game data every
frame making the game run faster | b. | When we use a timer to update the game’s data, we free it
from the frame rate of the system it’s playing on | d. | none of the above | | | | |
|

Trigonometry is defined as the study of a. | triangles | c. | vectors | b. | right triangles | d. | math | | | | |
|
|
|
14.
|
A
right triangle... a. | Is defined as
any triangle that has a hypotenuse | c. | Is defined as any triangle that has one right
angle | b. | Is defined as any triangle that has one hypotenuse and two
legs | d. | both b and
c | | | | |
|
|
|
15.
|
Typically legs are labeled a and b in a right triangle and the hypotenuse is labeled
c. The angles are labeled... a. | A, B, C and the label of each angle corresponds to the side
that it opposes | c. | A, B, C and the
label of each angle corresponds to the leg labels as well as the hypotenuse
respectively | b. | A, B, C and the label of each angle corresponds to the leg
label | d. | both a and
c | | | | |
|
|
|
16.
|
The
idea that the length of the hypotenuse c, when squared (c2), is equal to the sum of the
squares of the sides (a2 + b2) was discovered by... a. | A 6th century
philosopher and mathemetician named Pythagoras | c. | A 6th century philosopher and mathemetician named George
Boole | b. | A 6th century philosopher and mathemetician named
Buchanan | d. | none of the
above | | | | |
|
|
|
17.
|
Consider the following graph (Figure A)...
Figure A
...to get the length of side b you would solve for b
by... a. | b = Ax -
Bx | c. | b = By -
Ay | b. | b = Bx -
Ax | d. | b = Ay -
By | | | | |
|
|
|
18.
|
Considering the Graph on Figure A, to solve for c
you would take the square root of the following.... a. | (Bx -
Ax)2 + (By - Ay)2 =
c2 | c. | (Bx -
Ax) + (By - Ay) = c2 | b. | (Ax -
Bx)2 + (Ay - By)2 =
c2 | d. | (Bx -
Ax)2 + (By - Ay)2 =
c | | | | |

Angles on the Cartesian plane are drawn starting at the X axis. These angles are
given in degrees. The angle is usually labeled... a. | theta
(™) | c. | sigma (S) | b. | delta (D) | d. | beta (B) | | | | |
|
|
|

|
In a
sine function, the ______________ is the distance that a function travels before beginning to repeat
itself.
|
|
|
21.
|
The
following graph is a representation of a ________________ in trigonometry.
a. | sine | c. | arcsine | b. | cosine | d. | arccosine | | | | |
|
|
|
22.
|
SOHCAHTOA is a mnemonic device that tells us ... a. | the
relationship of the sides to the hypotenuse regardless of the lengths of the
sides | d. | both a and
b | b. | the
relationship of the legs to the hypotenuse regardless of the lengths of the
legs | e. | none of the
above | c. | the relationship of the sides to theta (angles) regardless of
the lengths of the sides | | | | |
|
|
|
23.
|
You
would use SOHCAHTOA to ... a. | find the length of the unkown side given you have the length of
one side and you know an angle | c. | inverse trigonometric functions | b. | find the angle
since we know the lengths of the sides | d. | both a and c | | | | |
