LWJGL 3 Line Positioning issues
« on: September 29, 2017, 18:28:30 »

My lines for my checkbox check vary with position, Here is one at (50, 70)

And here is one at (10, 70)


My Code:

CheckBox render method:
Lines 11 & 12 have check drawing code.
Code: [Select]
@Override
public void render() {
GLDrawHelper.color(borderColor);
GLDrawHelper.drawRect(area);
ScreenRect2D area2 = area.subtract(2);
GLDrawHelper.color(color);
GLDrawHelper.drawRect(area2);
if (pressed) {
ScreenRect2D area3 = area2.subtract(2);
GLDrawHelper.color(pressedColor); //from here
GLDrawHelper.drawLine(area3.getUpperRight(), area3.getLowerLeft().add(area3.getLowerLeft().x / 2, 0));
GLDrawHelper.drawLine(area3.getLowerLeft().add(area3.getLowerLeft().x / 2, 0), area3.getUpperLeft().subtract(0, (area3.getLowerLeft().y / 4) - area3.getUpperLeft().y / 2));//to here
}
GLDrawHelper.color(Color.BLACK);
GLDrawHelper.drawString(text, area.getLowerLeft().subtract(0, area.getHeight() / 2).subtract(-15, GLDrawHelper.getHeight(text, scale) * 2), scale);
}
GLDrawHelper drawLine
Code: [Select]
public static void drawLine(ScreenPos2D pos1, ScreenPos2D pos2) {
GL11.glBegin(GL11.GL_LINES);
GL11.glVertex2d(pos1.x, pos1.y);
GL11.glVertex2d(pos2.x, pos2.y);
GL11.glEnd();
}
ScreenRect2D(area)
Code: [Select]
public class ScreenRect2D {
public ScreenPos2D min, max;
public ScreenRect2D(ScreenPos2D min, ScreenPos2D max) {
this.min = min;
this.max = max;
}
public ScreenRect2D(double minX, double minY, double maxX, double maxY) {
this(new ScreenPos2D(minX, minY), new ScreenPos2D(maxX, maxY));
}
public boolean isInRect(double x, double y) {
return (x >= min.x) && (x <= max.x) && (y >= min.y) && (y <= max.y);
}
public ScreenPos2D getUpperLeft() {
return min;
}
public ScreenPos2D getUpperRight() {
return new ScreenPos2D(max.x, min.y);
}
public ScreenPos2D getLowerLeft() {
return new ScreenPos2D(min.x, max.y);
}
public ScreenPos2D getLowerRight() {
return max;
}
public double getHeight() {
return max.y - min.y;
}
public double getWidth() {
return max.x - min.x;
}
public ScreenRect2D add(double amount) {
return new ScreenRect2D(min.subtract(amount, amount), max.add(amount, amount));
}
public ScreenRect2D subtract(double amount) {
return add(-amount);
}
}
ScreenPos2D(min & max)
Code: [Select]
public class ScreenPos2D {
public double x, y;
public ScreenPos2D(double minX, double minY) {
this.x = minX;
this.y = minY;
}
public ScreenPos2D add(double x, double y) {
return new ScreenPos2D(this.x + x, this.y + y);
}
public ScreenPos2D add(ScreenPos2D pos) {
return add(pos.x, pos.y);
}
public ScreenPos2D subtract(ScreenPos2D pos) {
return add(-pos.x, -pos.y);
}
public ScreenPos2D subtract(double x, double y) {
return add(-x, -y);
}
}
