Unable to detect multiple Rect Collisions in Pygame

Asked 2022-Apr-10 at 05:13

I'm been working on a simple Pygame project that involves simulating motion sensor lights in open areas, and have created multiple instances of delivery riders, smokers and civilians. When users are within a certain distance, the lights on the ground would light up. The problem I faced was, when objects came into collision with the drivers, colliderect did not trigger at all (tested with print statements). Ideally all the civilians should collide and reflect off one another except the driver and smokers.

Getting last element on click every time in Javascript loop with Phaser JS

Asked 2022-Mar-31 at 12:55

I am making a game in Phaser although I believe the core of this issue is a lack of my JS understanding.

I am looping through a Phaser container and wish to apply a click handler on each child sprite, but when I execute the click on any of the sprites, it always returns the last child.

I have tried various suggestions on Stack Overflow eg here: JavaScript closure inside loops – simple practical example

but can never get the click to return anything other than the last item.

Can't figure out how to check mask collision between two sprites

Asked 2022-Mar-19 at 17:23

I have two different sprites in the same group, variables 'player' and 'ground'. They both are separate classes, with a mask of their surface. This line is in both of their classes.

...

ANSWER

Answered 2022-Mar-19 at 10:13

The sprites do not only need the mask attribute, they also need the rect attribute. the mask defines the bitmask and rect specifies the posiotion of the sprite on the screen. See pygame.sprite.collide_mask:

Tests for collision between two sprites, by testing if their bitmasks overla. If the sprites have a mask attribute, it is used as the mask, otherwise a mask is created from the sprite's image. Sprites must have a rect attribute; the mask attribute is optional.

If sprites are used in pygame.sprite.Groups then each sprite should have image and rect attributes. pygame.sprite.Group.draw() and pygame.sprite.Group.update() are methods which are provided by pygame.sprite.Group.

The latter delegates to the update method of the contained pygame.sprite.Sprites — you have to implement the method. See pygame.sprite.Group.update():

Calls the update() method on all Sprites in the Group. [...]

The former uses the image and rect attributes of the contained pygame.sprite.Sprites to draw the objects — you have to ensure that the pygame.sprite.Sprites have the required attributes. See pygame.sprite.Group.draw():

Draws the contained Sprites to the Surface argument. This uses the Sprite.image attribute for the source surface, and Sprite.rect. [...]

Phaser 3: Spritesheet doesn't load correctly

Asked 2022-Feb-23 at 05:57

I tried to add a spritesheet to my Phaser game the same way I've done it a few times before, however this time it seems to not load the images correctly, causing it to display a black & green square instead and causing it to throw an error when trying to play an animation.

Can anyone tell what is causing this issue?

The problem is, that you are using the wrong function, you should use this.anims.generateFrameNames, and not this.anims.generateFrameNumbers.

And set the correct key clean for the sprite.

QUESTION

How do you sort the render order of sprites in Flame (Flutter) at runtime?

Asked 2021-Oct-10 at 08:13

What's the most concise (and ideally, most efficient) approach to sort the rendering order of sprites in the game scene at runtime, post add()-ing the objects to the scene? Is there a built-in property on SpriteComponent or SpriteAnimationGroupComponent objects that can receive an int to indicate the sort order and override the implicit sort order? I wanted to confirm there wasn't something already implemented in Flame prior to implementing my own Z-sorting algorithm from scratch.

Thanks!

ANSWER

Answered 2021-Oct-10 at 08:13

The z-index order is called priority in Flame. If you know before you add the component to the game what priority it has, you can send in the named field priority to the constructor, like this:

You have to create a pygame.Surface, instead of creating a new window (pygame.display.set_mode).
The pixel format of the Surface must include a per-pixel alpha (SRCALPHA). The center point of the circle must be the center of the Surface. The radius must be half the size of the Surface:

QUESTION

The cause of uncontrolled camera movement in a mode 7 affine transformation?

Asked 2021-Jun-30 at 19:23

I am trying to implement a mode 7 effect with C and SDL2. Eventually, I hope to be able to do cool effects, like change the height and field of view. But for now, I just want to get something simple working. This is what I have so far:

My problem is that that upon turning, I seem to be heading in the same direction, even when I try to turn a different way. It's hard to get a picture of this, but upon running my code, it should become clear.

I am very confused why this is the case. My code is largely based off of this tutorial. I left comments in my C code describing the intent of each section. If you know why my attempt to emulate the SNES's mode 7 isn't working, please let me know. Note: to turn, press the left and right arrow keys, and to move forward and backward, press forward and back. This code may not work on non-Intel systems since I am depending on Intel SIMD intrinsics. I am using clang 12.0.5, if that helps.

Here is my mode_7 function which drives the effect:
