    <p>I'm making a 2D game with Processing, when I add a light, fps drops to 20~ from 30, if I add one more, it'll drop even more. But processing only uses %15 of cpu no matter what, how can I increase that, so I can see 30 fps?</p> <pre><code>void castLight(int mapNum){ color c = color(0, 0, 0); if(mapNum == 1){ for(int x = 0; x &lt; width; x++){ for(int y = 0; y &lt; height; y++){ if(improvedLights){ putShadow = improvedLights();//not working } else { putShadow = true; } for(int i = 0; i &lt; torchHolder1.size(); i++){ if(dist(x, y, torchHolderX1.get(i), torchHolderY1.get(i)) &lt;= maxDist){ if(improvedLights){ putShadow = improvedLights(); } else { putShadow = false; } } } if(putShadow){ int loc = x+y*width; float r,g,b; r = red (pixels[loc]); g = green (pixels[loc]); b = blue (pixels[loc]); r -= 100; g -= 100; b -= 100; r = constrain(r, 0, 255); g = constrain(g, 0, 255); b = constrain(b, 0, 255); if(torchAnimCounter % 31 &lt; 16){ c = color(r, g, b); } else { c = color(r+10, g+10, b+10); } pixels[y*width + x] = c; } } } for(int i = 0; i &lt; torchHolderX1.size(); i++){ for(int x = torchHolderX1.get(i) - maxDist; x &lt; torchHolderX1.get(i) + maxDist; x++){ if(x - maxDist &lt; torchHolderX1.get(i) &amp;&amp; x + maxDist &gt; torchHolderX1.get(i)){ torchCrossX = true; } else { torchCrossX = false; } for(int y = torchHolderY1.get(i) - maxDist; y &lt; torchHolderY1.get(i) + maxDist; y++){ if(y - maxDist &lt; torchHolderY1.get(i) &amp;&amp; y + maxDist &gt; torchHolderY1.get(i)){ torchCrossY = true; } else { torchCrossY = false; } float d = dist(x, y, torchHolderX1.get(i), torchHolderY1.get(i)); if(torchCrossX &amp;&amp; torchCrossY){ if(dist(x, y, torchHolderX1.get(i), torchHolderY1.get(i)) &lt;= maxDist){ if(x &gt; 0 &amp;&amp; x &lt; width &amp;&amp; y &gt; 0 &amp;&amp; y &lt; height){ int loc = x+y*width; float r,g,b; r = red (pixels[loc]); g = green (pixels[loc]); b = blue (pixels[loc]); float adjustBrightness = maxDist-d-100; r += adjustBrightness; g += adjustBrightness; b += adjustBrightness; r = constrain(r, 0, 255); g = constrain(g, 0, 255); b = constrain(b, 0, 255); if(torchAnimCounter % 31 &lt; 16){ c = color(r, g, b); } else { c = color(r+10, g+10, b+10); } pixels[y*width + x] = c; } } } } } } }//and same things goes for the second map </code></pre>

    1. COwe would appreciate more info about light because 2D geometry does not require lightning. How you set it up or what kind of light are you using? How many objects do you have in sketch? Maybe some snippet of code would be great.

    2. COI'm just adjusting brightness based on distance between light source and pixels, no shadows. I don't have much object in my sketch, at most 5-6 creature object and one player object. I'll try to put some snippet from codes that adjusts the brightness.(Waiting for 8 hours to pass)

    3. COIn general, i would guess it to be the amount of nested for loops in your draw() loop that is likely slowing down your program...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
