ParticleSimulation

On the screen, the moving elements are props, which come in 7 colors, corresponding to 7 different qualities (red being the heaviest, purple being the lightest).

On the left side is the control bar. Clicking or using the up and down arrow keys toggles between the following options:

"Mass", "Angle", "Particle Color", "Mode"

Each option has several optional values. The mouse wheel or left and right arrow keys can be used to switch between values. Different combinations of values for these 4 options may produce different effects when using the left mouse button. The effect is exactly the same for the right mouse button.

The "Mode" has 3 values: "Gravity", "Particle", and "Barrier". Different options correspond to different effects when clicking the mouse button.

The size of the "Mass" affects the strength of gravity in "Gravity" mode, as well as the particle generation speed and deletion range (right-click) in "Particle" mode. The size of the "Angle" affects the gravity angle in "Gravity" mode. The value of "Particle" affects the color of particles generated and deleted in "Particle" mode.

In addition to the mouse, you can also use the following keys to affect the potion:

Pressing q or z creates particles.

Pressing w or x deletes orders (not affected by the "Order" option).

Pressing s deletes all objects.

Pressing the number keys 0 to 7 changes the mass (color) of all particles.

Pressing a key consumes.

Pressing b accelerates particles.

Pressing c blocks props.

Pressing d makes particles move quickly.

Pressing e smashes things!

Pressing f restores time!

Other:

Right-clicking on the control bar options or pressing the spacebar restores default values.

（中文说明）

在屏幕上，移动的元素是道具，它们有7种颜色，对应7种不同的质量（红色最重，紫色最轻）。

左侧是控制栏。单击或使用向上和向下箭头键可以在以下选项之间切换：

“质量”，“角度”，“粒子颜色”，“模式”

每个选项都有任选的几个值。鼠标滚轮或左右箭头键可用于在值之间切换。使用鼠标左键时，这4个选项的不同值组合可能会产生不同的效果。鼠标右键的效果正好。

“模式”有 3 个值：“重力”、“粒子”和“屏障”。当单击鼠标按钮时，不同的选项对应不同的效果。

“质量”的大小会影响“重力”模式下的重力强度，以及“粒子”模式下的粒子生成速度和删除范围（右键单击）。“角度”的大小会影响“重力”模式下的重力角。“耳机”的值会影响“耳机”模式下面生成和删除耳机的颜色。

除了鼠标之外，您还可以使用以下按键来影响药剂：

按 q 或 z 键可创建粒子。

按 w 或 x 键可删除订单（不受“订单”选项的影响）。

按 s 键可删除所有对象。

按数字键 0 到 7 会改变所有粒子的质量（颜色）。

按一个键即可消耗。

按 b 键可加速粒子。

按c键可阻止道具。

按d键使粒子高速移动。

按e键砸东西！

按f键可恢复时间！

其他：

右键单击控制栏选项或按空格键可恢复默认值。
