I am making a game where i need to display ship traversing a flowing river. I am creating river with bezier curves but it is with only 3 control points from the bezerCurveTo. So, the river is not 'curvy enough.' How can i go about achieving this?
The tabageos.GeometricMath Class has some advanced functions for curves, paths and merging Arrays. To accomplish what you want you could join multiple paths together. For example: https://codepen.io/Contrapenner/pen/mdBVrbw
function dot(x, y) {
var d = document.createElement("span");
d.setAttribute("style", "position:absolute;left:" + x + "px;top:" + y + "px;width:2px;height:2px;background: blue");
document.getElementById("river").appendChild(d);
};
var riverPath = tabageos.GeometricMath.getRawArcCurvePath(5, 5, 10, 10, 5, 15, 10);
riverPath = tabageos.GeometricMath.mergeArrays(riverPath, tabageos.GeometricMath.getRawArcCurvePath(5, 15, 0, 20, 5, 25, 10));
riverPath = tabageos.GeometricMath.mergeArrays(riverPath, tabageos.GeometricMath.getRawArcCurvePath(5, 25, 10, 30, 5, 35, 10));
riverPath = tabageos.GeometricMath.mergeArrays(riverPath, tabageos.GeometricMath.getRawArcCurvePath(5, 35, 0, 40, 5, 45, 10));
//and you could keep going as needed.
//there is also getRawHermiteCurvePath
var i = 0;
for (i; i < riverPath.length; i += 2) {
dot(riverPath[i], riverPath[i + 1]);
}
