The floatSelector types have fine-tune and value-reset features. When used with a slideBar it can be set to fade the value in and out. It's used in the force control to vary the cross, drag and gravity forces being applied to the sparks. The buttStrip type is a button which opens/closes a single floatSelector. It's used in most of the controls seen in the demo. If Yspark > Ygraph in one position and Yspark so a single click strip (or slideBar) can be used to set numerous quantities. Sparks have a velocity data member (an sf::Vector2f) so the position last frame can be found. Both are demonstrated in the video.Ĭollision testing: A bounding box check is done 1st, then a ray based method is used to check if the spark has crossed the graph. Sparks are collision tested when incident from either side of the graph, so sparks can be contained within the interior area of the polar types or bounced off of the outside. The sine, polynomial and hyperbola examples are Cartesian. The defining function can be expressed in either Cartesian or polar coordinates. The 2 polygon types have 1+number-of-vertices sf::Vertex, also drawn as sf::LinesStrip. Graphically, all curved examples (sine, polynomial, hyperbola, ellipse and flower) are 100 or more sf::Vertex drawn as a sf::LinesStrip. ** The graphFuncs: see include/graphFunc.h and. The yellow dots are at the springs fixed end positions. Interactions with 2 springs is also shown. Gravity is acting in most of the demo video. They have mass and can be acted on by applied forces. They collide only with the graphFunc types. The sparks are not mutually interacting so we can have thousands without performing millions of collision tests each frame. Graphically each is an sf::Quad drawn from a texture (see dots9.png in the images folder). cppĪlthough the image size is variable each is treated as a point object. ** The spark type: see include/spark.h and. The particle interactions are shown first, followed by the card game. Gravity, drag, curl, spring and/or inverse square forces can be applied to the sparks.Ī force control allows variance of the force magnitudes, as well as parameters for the spring forces such as spring stiffness, rest length and the position of the attraction centers. The typename for the particles is 'spark', hence the 'spark' control in the video. In the particle physics level each function graph has a control which allows rotation of the graph, variation of parameter values and for the curve to have motion. When an ace through king set is formed an animatioon collapses the set, then moves it to a complete set pile. The side lengths are varied during the flip to create some perspective, making it appear to flip left side over right. When a facedown card is revealed a flip over animation occurs. The card deals and movement between columns are animated. I've also made a line emitter which prints particles like a dot matrix printer. Any function can be defined in Cartesian or polar coordinates. Level and GUI classes are also developed.Ī function graphing class is developed and used for particles to collide with. Particle emission and collision handling grew from this effort. The game ends in a fireworks show on a win so some particle effects were needed. I wanted a version of Spider Solitaire to play which is similar to the windows XP version so I've made my own. All gaps (empty spaces) in the tableau have to be filled before the deal.Hi everyone. When you have made all the available plays on the board, click on the stock pile to deal one card on each tableau pile. When any of tableaus are empty you can fill space with any card or group of cards. Groups of cards in sequence down by following suit may be moved as a unit. One card at a time can be moved from pile to pile. You can build tableau piles down regardless of suit, ending at Ace.You can not build a King on an Ace. Top cards of tableau piles are available to play. The object of the game is to build 8 sequences down in suit within the tableau (each running from King to Ace) and then move them to 8 foundations. 54 cards are dealt to these piles (6 cards are dealt to first four piles and 5 cards to the remaining ones). Spider solitaire uses two decks (104 cards). DetailsSpider solitaire ( solitaire or patience ) is a well-known solitaire game, which has gained a lot in popularity since Microsoft have started shipping it free with windows.
