不用加图片！

太感谢了！

小改了一点 刚刚稍微测试了下 在640X480或者更高分辨率下光源暂时没有任何问题了  可以随着分辨率提高而自适应描绘的大小，以后在更换分辨率就不会出现类似的情况啦

24. # * Features
    
25. #-------------------------------------------------------------------------------
    
26. # - Realistic Light
    
27. # - Light does not pass over walls, blocks and roofs
    
28. # - Static Light Sources
    
29. # - Dynamic Light Sources (like a player's lantern)
    
30. # - Multiple effects
    
31. # - Easy to use (comments)
    
32. #
    
33. #-------------------------------------------------------------------------------
    
34. # * WARNING - Performance
    
35. #-------------------------------------------------------------------------------
    
36. # This script may be too heavy to old processors! The Awesome Light Effects was
    
37. # tested on a Core 2 Duo E4500 and on a Core i5, without any lag. However,
    
38. # there's other factors that may influence the script performance:
    
39. #
    
40. # 1. Map size
    
41. # This script searches surfaces on the map, in order to cut the light pictures.
    
42. # In a huge map, the number of surfaces may increase a lot, affecting the
    
43. # DYNAMIC LIGHT SOURCE only. Map size does not influence the static sources.
    
44. #
    
45. # 2. Number of effects
    
46. # This script draws the effects on the screen, but before drawing, it checks
    
47. # if the effect is out of screen (in this case, the script will skip the
    
48. # light drawing). Too much effects may cause lag, but this is just a prevision.
    
49. #
    
50. # 3. Effect's picture size
    
51. # The picture size of the DYNAMIC LIGHT SOURCE influences directly on your
    
52. # game's performace. The bigger is the picture, the slower it will be to
    
53. # draw it dynamically. The recommended maximum size is 200x200 pixels
    
54. #
    
55. #-------------------------------------------------------------------------------
    
56. # * WARNING - Light pictures
    
57. #-------------------------------------------------------------------------------
    
58. # In order to run this script correctly, the light pictures MUST obey the
    
59. # following conditions:
    
60. # 1. The picture's size MUST be multiple of 2. Example: 150x150
    
61. # 2. The picture's width MUST be equal to it's height. Example: 156x156
    
62. # 3. The picture's colors MUST be inverted! This is necessary because
    
63. #    the script inverts the colors to draw the effect. The black color
    
64. #    will be transparent!
    
65. #
    
66. #-------------------------------------------------------------------------------
    
67. # * Instructions - 1. Setup your effects!
    
68. #-------------------------------------------------------------------------------
    
69. # In order to setup your static effects, go to the setup part and define your
    
70. # effects inside the Effects hash. Do as the following mode:
    
71. #
    
72. # X => [picture,opacity,variation,cut],   <= Remember to put a comma here!
    
73. #
    
74. # Where:
    
75. # picture => Picture's name, inside the Graphics/Lights folder;
    
76. # opacity => Effect's opacity;
    
77. # variation => Effect's opacity variation;
    
78. # cut => Put true to cut the effect or false to don't;
    
79. # X => The effect's ID, it will be used on events.
    
80. #
    
81. # Check the default effects to understand how they work.
    
82. #
    
83. #-------------------------------------------------------------------------------
    
84. # * Instructions - 2. Use your effects!
    
85. #-------------------------------------------------------------------------------
    
86. # In order to use a effect, put the following comment on a event:
    
87. #
    
88. # [light x]
    
89. #
    
90. # Where x must be the Effect's ID.
    
91. #
    
92. #-------------------------------------------------------------------------------
    
93. # * Instructions - 3. Use an awesome lantern!
    
94. #-------------------------------------------------------------------------------
    
95. # The dynamic light source (lantern) is initialized invisible by default.
    
96. # You may call the following commands:
    
97. #
    
98. # l = $game_map.lantern
    
99. # Gets the lantern into a variable
    
100. 
     
101. # l.set_graphic(i)
     
102. # Sets the lantern's graphic to i, where i must be the picture's file name on
     
103. # Graphics/Lights folder.
     
104. #
     
105. # l.set_multiple_graphics(h)
     
106. # Sets the lantern's graphics to h, where h must be a hash with the following
     
107. # structure:
     
108. #
     
109. # h = {2=>"ld",4=>"ll",6=>"lr",8=>"lu"}
     
110. #
     
111. # Where:
     
112. # "ld" is the name of the picture when the lantern's owner is looking down;
     
113. # "ll" is the name of the picture when the lantern's owner is looking left;
     
114. # "lr" is the name of the picture when the lantern's owner is looking right;
     
115. # "lu" is the name of the picture when the lantern's owner is looking up.
     
116. #
     
117. # l.change_owner(char)
     
118. # Sets the lantern's owner to char. Char must be ONE of the following commands:
     
119. # $game_player           <= The player itself;
     
120. # self_event             <= The event where the command was called;
     
121. # $game_map.events[x]    <= The event ID x.
     
122. #
     
123. # l.set_opacity(o,p)
     
124. # Sets the lantern's opacity, where:
     
125. # o is the opacity itself;
     
126. # p is the opacity variation.
     
127. #
     
128. # l.show
     
129. # After setting the lantern with the commands above, you may set it to visible
     
130. # using this command.
     
131. #
     
132. # l.hide
     
133. # Use this command to set the lantern as invisible.

136. # * Instructions - 4. Use the effect's surface!
     
137. #-------------------------------------------------------------------------------
     
138. # The Awesome Light Effects draws the effects on a surface. In order to make
     
139. # the effects visible, the effect's surface MUST be visible. The Effect's
     
140. # Surface is initialized with it's opacity set to zero. You can call the
     
141. # following commands:
     
142. #
     
143. # s = $game_map.effect_surface
     
144. # Gets the Effect's Surface into a variable
     
145. #
     
146. # s.set_color(r,g,b)
     
147. # Changes the Effect's Surface color instantly, where:
     
148. # r => red level;
     
149. # g => green level;
     
150. # b => blue level;
     
151. #
     
152. # s.set_alpha(a)
     
153. # Changes the Effect's Surface opacity instantly to a.
     
154. #
     
155. # s.change_color(time,r,g,b)
     
156. # Changes the Effect's Surface color ONLY in a certain time, where:
     
157. # time => The change's time (frames);
     
158. # r => red level;

177. #-------------------------------------------------------------------------------
     
178. # You can access the Effect's Surface with the "Screen Tone" command. In order
     
179. # to turn this feature on, set the "Surface_UE" constant to true.
     
180. #
     
181. # If you decided to use this feature, please note some details:
     
182. # 1. The colors values must be between 0 and 255;
     
183. # 2. The time is in frames;
