Sorry about the long instructions, I was being thorough. In most cases, you can jump in and use the program, but you might find the instructions useful even after you think you figured it all out. Instructions: - Shift-Click the Green Flag to toggle Turbo Mode (Recommended but not necessary). - Click on unselected bodies (planets, stars, satellites, astroids, or other celestial objects) to select them. Click on selected bodies to deselect them. Click on the empty region to deselect all bodies. Click-&-drag the only selected body, if any, to move it. Click-&-drag one of the more than one selected bodies to move all selected bodies as a group. You can click-&-drag a non-selected body, but other selection/s, if any, will deselect itself/themselves. If only one body is selected, a slider will pop up. Drag the slider to change the mass of the body. Drag clockwise to increase the mass, likewise, drag counter-clockwise to decrease the mass. Drag away from the body to fine tune the mass. Drag toward the body (but not too close otherwise the slider will become too sensitive) to snap to one of five black indentations as can be seen on the slider. - Click on the gadget in the lower-right corner to turn on the options. Click on the x in the upper-right corner to turn off the options. Bodies cannot be interacted with when options is turned on. Please note that all selected body/bodies, if any, will be deselected upon turning on options. - Options: - Use the red green switch in the lower left corner to hide or show the planets via a click or a click-&-drag. - Use the radio buttons in the upper-left corner to view both, direction, or acceleration in that order from top to bottom.
Do not "See Inside" unless you have sufficient experience in programming because the content within is enough to make an inexperienced programmer to give up their ambition with exasperation and haste. I'm kidding, kinda. How to read the map: - The darker the region, the smaller the acceleration (gravitational pull). The brighter the region, the bigger the acceleration. - Red hue regions have a downward acceleration. Yellow-green hue regions have a leftward acceleration. Magenta-blue hue regions have a rightward acceleration. Cyan hue regions have an upward acceleration. I used Isaac Newton's Universal Law of Gravitation (Inverse-Square Law to be more precise) to simulate the map. I find it interesting to note that there are dimples of black regions between the bodies. I would like to know what you think is the reason those black regions exist in my program. Versions: - 1.0.1: - Selecting the blue body resulted with another body/bodies, if any, deselecting itself/themselves. Fixed.
