A particle sandbox which has tools, types, and world settings.

Tools that I have in the sandbox are:

Brush: It spawns particles at the cursor location

Erase: It removes particles at the cursor location

Repel: It repels particles at the cursor location when dragging

Particle types that I have are:

Default: not too special, just a circle using the world settings

Fire: it floats, and then fades to create smoke

Smoke: it floats and fades away

Snow: it falls slowly and piles up when it hits the canvas floor

Bubble: it floats and increases its size over time

Water: it falls and behaves like realistic water, moving horizontally

Sand: it falls and piles up, tries to go under water

World Settings that I have are:

Gravity: Affects how fast SOME particles fall, not all

Wind: Causes particles to move left or right

Spawn Rate: Makes particle spawn faster/slower with the brush tool

Brush Size: Controls how large of an area particles spawn in with the brush tool

Opacity: Affects how transparent SOME particles are

Color: Affects the color of ONLY defauly particles

Cell Size: Controlls the invisible/visible grid size, making particle more small or larger indirectly, also clears particles when tinkering with it

Grid Toggle: Shows/hides the grid

Clear: clears all particles on the canvas

Reset settings: Sets all the settings back to default
