Creates the PlayThing and sets sprite to 0 if any sprites were given
Instance methods
angle
The PlayThing's angle in degrees.
0 points up.
All ways to set will keep the value between 0 and 360
Sets the angle and removes all 360's from the number to ensure it is between 0 and 359
collision_flags
The flags to use for collision detection
collision_flags=(collision_flags : CollisionFlags)
The flags to use for collision detection
destroy
Destroys a plaything (No more displaying or collision calls)
flags
The flags for the plaything
The flags for the plaything
flipbook
The flipbook to animate the sprites. Will always overwrite sprite if active
flipbook=(flipbook : Flipbook)
The flipbook to animate the sprites. Will always overwrite sprite if active
Moves in x, y direction. X and Y are speeds.
Clamps between 0 and screen width/height
on_collide
Called when an overlap between this plaything (pt) and another plaything (other) occurs
on_collide=(on_collide :
Proc(
PlayThing,
PlayThing,
Nil))
Called when an overlap between this plaything (pt) and another plaything (other) occurs
on_collide_end
Called once when an overlap stops
on_collide_end=(on_collide_end :
Proc(
PlayThing,
PlayThing,
Nil))
Called once when an overlap stops
on_collide_start
Called once when an overlap starts
on_collide_start=(on_collide_start :
Proc(
PlayThing,
PlayThing,
Nil))
Called once when an overlap starts
right_vector
The right direction of the PlayThing.
A PlayThing with 0 angle will have right_vector {1, 0}
Rotates in rot direction, going clockwise
sprite
The sprite to display from sprites
Sets the current sprite number in sprites to display
sprites
An array of all sprites for the PlayThing to display
unmove
Sets the position to the previous x and y values
up_vector
The upwards direction of the PlayThing.
A PlayThing with 0 angle will have up_vector {0, 1}
x
The PlayThing's location. Bottom left centered.
All ways to set clamp between 0 and Tsh.res_x/Tsh.res_y
Sets the x position and clamps it between 0 and the screen's width
Sets the y position and clamps it between 0 and the screen's height
