Here are some functions that I use to draw shapes on the Construct 2 renderer.
renderSquare(this, renderer,cr.RGB(0,0,255));[/code:3573wm0c]
[code:3573wm0c]function renderSquare(inst, renderer,color) {
var q = inst.instance.GetBoundingQuad();
renderer.Outline(q, color);
}[/code:3573wm0c]
Circle:
[code:3573wm0c]renderCircle(this, renderer,cr.RGB(0,0,0),18);[/code:3573wm0c]
[code:3573wm0c]
function renderCircle(inst, renderer, color,segments) {
var q = inst.instance.GetBoundingQuad();
var xpos = (q.tlx + q.trx + q.blx + q.brx) / 4;
var ypos = (q.tly + q.try_ + q.bly + q.bry) / 4;
xsto = new cr.vector2(inst.instance.GetSize().x / 2, 0);
ysto = new cr.vector2(inst.instance.GetSize().y / 2, 0);
rcos = Math.cos((Math.PI / (segments/2)))
rsin = Math.sin((Math.PI / (segments/2)))
for (var i = 0; i < segments; i++) {
xsto.x = ysto.x * rcos - ysto.y * rsin;
xsto.y = ysto.x * rsin + ysto.y * rcos;
renderer.Line(new cr.vector2(xpos + xsto.x, ypos + xsto.y), new cr.vector2(xpos + ysto.x, ypos + ysto.y), color);
q.tlx = xpos + xsto.x;
q.tly = ypos + xsto.y;
q.trx = xpos + ysto.x;
q.try_ = ypos + ysto.y;
q.blx = xpos;
q.bly = ypos;
q.brx = xpos;
q.bry = ypos;
ysto = new cr.vector2(xsto.x, xsto.y);
}
}

Polyline:
[code:3573wm0c]drawPolyline("641 96 435 99 434 186 634 181 641 95 688 45 689 138 633 180 435 98 513 50 688 45",cr.RGB(255, 0, 0), this.instance,renderer);[/code:3573wm0c]
[code:3573wm0c]function drawPolyline(points,color, inst,rend)
{
var q = inst.GetBoundingQuad();
var xpos = (q.tlx + q.trx + q.blx + q.brx) / 4;
var ypos = (q.tly + q.try_ + q.bly + q.bry) / 4;
var fq = new cr.quad;
var diffx,diffy;
var pArray = [];
pArray = points.split(" ");
if (xpos > pArray[0]) {
diffx = xpos - pArray[0];
diffx *= -1;
} else {
diffx = pArray[0] - xpos;
}
if (ypos > pArray[1]) {
diffy = ypos - pArray[1];
diffy *= -1;
} else {
diffy = pArray[1] - ypos;
}
for (var i = 0; i < pArray.length; i += 2) {
rend.Line(new cr.vector2(pArray[i] - diffx, pArray[i + 1] - diffy), new cr.vector2(pArray[i + 2] - diffx, pArray[i + 3] - diffy), color);
}
