Legacy GM How Do We Draw A Physics "Fixture"?

[JeZxLee]

Hi,

We are trying to get a some small colored balls to fall.
We are using physics "Fixtures" and "Objects" and trying to do physics in script code.

Here is our current code which runs and does not show any errors:
________________________________________________________________
// Initialize code:
global.NumberOfColoredBalls = 0;
for (var index = 0; index < 99; index+=1)
{
global.ColoredBallFixtureIndex[index] = physics_fixture_create();
global.ColoredBallMyFixtureIndex[index] = -1;
global.ColoredBallSpriteIndex[index] = 0;
global.ColoredBallScreenX[index] = 0;
global.ColoredBallScreenY[index] = 0;
global.ColoredBallDirectAngle[index] = 0;
global.ColoredBallSpeed[index] = 0;
}
________________________________________________________________
// Game logic code:
else if (global.PlayerStatus == End)
{
for (var indexY = 0; indexY < 3; indexY+=1)
{
for (var indexX = 0; indexX < 4; indexX+=1)
{
if (global.PlayfieldScale[indexX, indexY] > 0) global.PlayfieldScale[indexX, indexY]-=.1;
else global.PlayfieldScale[indexX, indexY] = 0;
}
}

global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] = global.ColorToChoose;
global.ColoredBallScreenX[global.NumberOfColoredBalls] = global.BigColorToChooseScreenX;
global.ColoredBallScreenY[global.NumberOfColoredBalls] = global.BigColorToChooseScreenY+100;

var inst;
physics_fixture_set_circle_shape(global.ColoredBallFixtureIndex[global.NumberOfColoredBalls], 16);
physics_fixture_set_density(global.ColoredBallFixtureIndex[global.NumberOfColoredBalls], 1.0);
if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 1) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectRedObject);
else if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 2) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectOrangeObject);
else if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 3) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectYellowObject);
else if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 4) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectGreenObject);
else if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 5) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectBlueObject);
else if (global.ColoredBallSpriteIndex[global.NumberOfColoredBalls] == 6) inst = instance_create(global.ColoredBallScreenX[global.NumberOfColoredBalls], global.ColoredBallScreenY[global.NumberOfColoredBalls], SelectPurpleObject);
global.ColoredBallMyFixtureIndex[global.NumberOfColoredBalls] = physics_fixture_bind(global.ColoredBallFixtureIndex[global.NumberOfColoredBalls], inst);

global.PlayerStatus = Begin;
SetupColorToChooseAndPlayfield();
}

Our problem now is the newly created Fixtures are not being drawn on the game screen?
How can we draw the Fixtures?

Thanks!

Hi Again!

We need help, the code looks good and builds and runs, but the new physics "Fixtures" are not being drawn on the screen.
How do we draw the new physics "Fixtures"?
Do we draw fixtures or do we draw objects?
I don't see drawing functions in help for fixtures or objects.
Thanks!

Generally, what's drawn automatically is the sprite assigned to the instance -- not the fixture that's bound to it. Alternatively, you can draw something different by putting code in the DRAW event.

Either way, fixtures are not automatically drawn, other than in the "debug" mode.

Hi!

Ok, so we tried to run the game in DEBUG mode - the physics fixtures are still not being drawn?
Can someone look at above code to see if we do something wrong?
Thanks!
