CODE

clear sp = new Sprite sp.image = file.loadImage("/sys/pics/Block.png") sp.x = 600 sp.y = 500 sp.scale = [3,1] sp.localBounds = new Bounds sp.localBounds.width = sp.image.width sp.localBounds.height = sp.image.height display(4).sprites.push sp wasDown = false while true // press Control-C to exit isDown = mouse.button if sp.contains(mouse) then sp.tint = "#CCCCFF" if isDown and not wasDown then print "Sprite clicked!" end if else sp.tint = color.white end if wasDown = isDown yield end while 

EXPLANATION

LINE 1-6 & 9

Lines 1-6 and line 9 are dedicated to rendering sprites, a process I have already explained in detail in this blog.
How to render sprite
Since I’ve already covered how they work in a previous post, I won’t be explaining them again here.

sp.localBounds = new Bounds
sp.localBounds.width = sp.image.width
sp.localBounds.height = sp.image.height

sp.localBounds = new Bounds - Creates a new local boundary for sp

sp.localBounds.width = sp.image.width
sp.localBounds.height = sp.image.height - Sets width and height of boundary we just created

LOOP PART
If you’ve programmed in any language before, this should be easy to understand. But if MiniMicro is your first programming language, this might look like a wizard’s spell. No worries—let’s understand it together using this chart.

"This graph doesn't tell what the whole loop is about, but it helps in understanding the result of the condition applied.

Another condition used in this program is in line:
if sp.contains(mouse) then
sp.tint = "#CCCCFF"

This condition checks if the mouse pointer is hovering over the sprite (sp.contains(mouse)). If true, it changes the sprite’s tint color to #CCCCFF
