Moving Spike Block > 2D

unklnik published on 2024-01-06 included in category Go and series

Moving Spike Block

This demonstrates how to create a moving block with four spikes that move along with the block and cause damage when the moving spikes collide with the player rectangle. To complete this example you will need to download the tile sheet here. WASD keys move the player, SPACE key to create a new room, UP arrow key to change zoom and F1 key to turn on debug mode which will display rectangle outlines instead of images. View on Github

Move to Point with Collisions > 2D

Move to Point with Collisions

This demonstrates how to move a player (or other object) to a point as determined by clicking on the screen. Left mouse click on the screen and the green rectangle will move to the point, recalculating X & Y directions as it moves therefore moving smoothly. If the player (green rectangle) collides with a blue block it will adjust movement accordingly, however, note that this does not find paths. This will purely stop either X or Y, or both, movement directions, dependent on the angle of movement. This example is based on the previous example Move to Point which does not take collisions into account which can be used as a starting point to complete this example. View on Github

Move to Point

This demonstrates how to move a player (or other object) to a point as determined by clicking on the screen. Left mouse click on the screen and the green circle will move to the point, recalcuting X & Y directions as it moves therefore moving smoothly. Note that this does not take into account collisions with other objects, if you would like to also check for collisions whilst moving then this example includes collision checking. View on Github

Fake Candlelight

This demonstrates how to create the illusion of flickering candles in 2D using gradient filled circles. To complete this example you will need to download the candle image here. Note that this is not actually lighting, DOWN arrow key changes light color. View on Github

I am a self taught Go programmer and do it as a hobby, the code below is my own interpretation of how to do something, probably not the only way or the best way.

Simple way to explode blocks

This is an easy way to create an illusion of blocks exploding using a slices of structs that contain fade, color, rectangles and movement direction. Pressing SPACE key will create a slice of smaller blocks with random directions that fade away. Once the timer ends then it will reset and create more blocks. View on Github
